Arms race


The German industrial base had, by 1914, overtaken that of Britain, though Germany did not have the commercial advantages of a large empire. In the years running up to the war a race to possess the strongest navy arose between Britain and Germany, each country building large numbers of dreadnoughts. The naval race between Britain and Germany was intensified by the 1906 launch of HMS Dreadnought

The sixth HMS Dreadnought of the Royal Navy was a battleship that revolutionised naval power when she entered service in 1906.

The cost of the arms race was felt in both Britain and Germany. The total arms spending by the six Great Powers (Britain, Germany, France, Russia, Austria-Hungary and Italy) increased by 50% between 1908 and 1913.

Russia's Plan 19 foresaw a concurrent mobilization of its armies against Austria-Hungary, Germany, and the Ottomans, while Plan 19 Revised saw Austria-Hungary as the main target, reducing the initial commitment of troops against East Prussia.

All three plans created an atmosphere in which speed was thought to be one of the determining factors for victory. Elaborate timetables were prepared; once mobilization had begun, there was little possibility of turning back. Diplomatic delays and poor communications exacerbated the problems.

Also, the plans of France, Germany and Russia were all biased toward the offensive, in clear conflict with the improvements of defensive firepower and entrenchment.

This platform provided some justification for the American entry into the war when the Russian Empire surrendered in 1917.

The Allies consisted of Great Britain and France, both democracies, fighting the Central Powers, which included Germany, Austro-Hungary, and the Ottoman Empire. Russia, one of the Allied Powers, was an empire until 1917, but it was opposed to the subjugation of Slavic peoples by Austro-Hungary. Against this backdrop, the view of the war as one of democracy versus dictatorship initially had some validity, but lost credibility as the conflict continued.

 famously put most of the blame on Germany's aristocratic leaders. He argued that the German leaders thought they were losing power and time was running out. The German social democratic party had won several elections, increasing their voting share and had by 1912 become the most represented party in Germany. While the elected institutions had little power compared with the Kaiser it was feared that some form of political revolution was imminent. Russia was in midst of a large scale military build-up and reform which was to be completed in 1916-17. A war would unite Germany and defeat Russia before this. In his later works Fischer went further and argued that Germany had planned the war in 1912.

Historian Samuel R. Williamson has emphasized the role of Austria-Hungary. Convinced that Serbian nationalism and Russian Balkan ambitions were disintegrating a monarchy comprising eleven different nationalities, Austria-Hungary hoped for a limited war against Serbia and that the strong German support would force Russia to keep out of the war and weaken its Balkan prestige.

Balance of power


One of the goals of the foreign policies of the Great Powers in the pre-war years was to maintain the 'Balance of Power' in Europe. This evolved into an elaborate network of secret and public alliances and agreements. For example, after the Franco-Prussian War
Franco-Prussian War

The Franco-Prussian War or Franco-German War, often referred to in France as the 1870 War was a conflict between Second French Empire and Kingdom of Prussia, while Prussia was backed by the North German Confederation, of which it was a member, and the South German states of Grand Duchy of Baden, History of W?rttemberg#The Kingdom...
 (1870–71), Britain seemed to favour a strong Germany, as it helped to balance its traditional enemy, France. After Germany began its naval construction plans to rival that of Britain, this stance shifted. France, looking for an ally to balance the threat created by Germany, found it in Russia. Austria-Hungary, facing a threat from Russia, sought support from Germany.

When World War I broke out, these treaties only partially determined who entered the war on which side. Britain had treaties with France or Russia, entering the war on their side. Italy had a treaty with both Austria-Hungary and Germany, yet did not enter the war with them; Italy later sided with the Allies. Perhaps the most significant treaty of all was the initially defensive pact between Germany and Austria-Hungary, which Germany in 1909 extended by declaring that Germany was bound to stand with Austria-Hungary even if it had started the war.

July crisis and declarations of war

The Austro-Hungarian government used the assassination of Archduke Franz Ferdinand as a pretext to deal with the Serbian question, supported by Germany. On 23 July 1914, an ultimatum was sent to Serbia with ten demands, some so extreme that the Serbian reply included reservations and rejected the sixth demand. The Serbians, relying on support from Russia, removed acceptance of the sixth key demand (the draft reply had accepted it), and also ordered mobilization. In response, Austria-Hungary issued a declaration of war on 28 July.

On July 29th and 30th, Russia began its mobilization directed at the Austrian frontier.

On July 30th, Helmuth von Moltke (the younger)

, Germany's Chief of General Staff, announced a "state of imminent war danger". The next day Russia completed its mobilization, but still maintained that it would not attack if peace talks were to begin. Germany then replied that Russia must demobilize within the next twelve hours.

On the night of 30/31 July when handed a document stating that Russia would not cancel its mobilisation, German Kaiser Wilhelm II wrote a lengthy commentary containing the startling observations:
"For I no longer have any doubt that England, Russia and France have agreed among themselves - knowing that our treaty obligations compel us to support Austria - to use the Austro-Serb conflict as a pretext for waging a war of annihilation against us. ... Our dilemma over keeping faith with the old and honorable Emperor has been exploited to create a situation which gives England the excuse she has been seeking to annihilate us with a spurious appearance of justice on the pretext that she is helping France and maintaining the well-known Balance of Power in Europe, i.e. playing off all European States for her own benefit against us."


On 31 July, after the Russian General Staff informed Russian Emperor Nicholas II that partial mobilization was logistically impossible, a full mobilization was ordered.

On August 1, German discussions regarding declaring war on Russia were interrupted when at 4:23PM a telegram from the German Ambassador to Britain arrived with a planned British proposal to guarantee the neutrality of France and thus limit the war to one fought in the east. Despite opposition from the German military, Germany immediately accepted the proposal by telegrams at the ambassadorial and royal levels." In keeping with this decision, Kaiser Wilhelm II demanded his generals shift the mobilization to the east. Helmuth von Moltke (the younger)

The British soon realized the stupidity of their proposal and backed out of it using the face-saving device of saying their proposal was misunderstood. The net effect of this incident was to modestly disrupt the German mobilization and war plan in the west. Germany and France mobilized nearly simultaneously.

Chronology


Opening hostilities


Confusion among the Central Powers
The strategy of the Central Powers suffered from miscommunication. Germany had promised to support Austria-Hungary’s invasion of Serbia, but interpretations of what this meant differed. Austro-Hungarian leaders believed Germany would cover its northern flank against Russia. Germany, however, envisioned Austria-Hungary directing the majority of its troops against Russia, while Germany dealt with France. This confusion forced the Austro-Hungarian Army

Over the next two weeks Austrian attacks were thrown back with heavy losses, which marked the first major Allied victory of the war and dashed Austrian hopes of a swift victory. As a result, Austria had to keep sizable forces on the Serbian front, weakening its efforts against Russia.

Despite this, communications problems and questionable command decisions cost Germany the chance of obtaining an early victory.

, the Allies made several attempts to break through German lines. At the tactical level, the German defensive doctrine was well suited for trench warfare, with a relatively lightly defended "sacrificial" forward position, and a more powerful main position from which an immediate and powerful counter-offensive could be launched. This combination usually was effective in pushing out attackers at a relatively low cost to the Germans. In absolute terms, of course, the cost in lives of men for both attack and defense was astounding.

Ludendorff wrote on the fighting in 1917, "The 25th of August concluded the second phase of the Flanders battle. It had cost us heavily…. The costly August battles in Flanders and at Verdun imposed a heavy strain on the Western troops. In spite of all the concrete protection they seemed more or less powerless under the enormous weight of the enemy’s artillery. At some points they no longer displayed the firmness which I, in common with the local commanders, had hoped for. The enemy managed to adapt himself to our method of employing counter attacks… I myself was being put to a terrible strain. The state of affairs in the West appeared to prevent the execution of our plans elsewhere. Our wastage had been so high as to cause grave misgivings, and had exceeded all expectation."

On the battle of the Menin Road Ridge Ludendorff wrote: "Another terrific assault was made on our lines on the 20 September…. The enemy’s onslaught on the 20th was successful, which proved the superiority of the attack over the defence. Its strength did not consist in the tanks; we found them inconvenient, but put them out of action all the same. The power of the attack lay in the artillery, and in the fact that ours did not do enough damage to the hostile infantry as they were assembling, and above all, at the actual time of the assault."

German U-boats attempted to cut the supply lines between North America and Britain. The nature of submarine warfare meant that attacks often came without warning, giving the crews of the merchant ships little hope of survival. The United States launched a protest, and Germany modified its rules of engagement. After the notorious sinking of the passenger ship RMS Lusitania

Fighting in India
The war began with an unprecedented outpouring of loyalty and goodwill towards the United Kingdom from within the mainstream political leadership, contrary to initial British fears of an Indian revolt. India under British rule contributed massively to the British war effort by providing men and resources. This was done by the Indian Congress in hope of achieving self-government as India was very much under the control of the British. The United Kingdom disappointed the Indians by not providing self-governance, leading to the Gandhiian Era in Indian history. About 1.3 million Indian soldiers and labourers served in Europe, Africa, and the Middle East, while both the Indian government and the princes sent large supplies of food, money, and ammunition. In all 140,000 men served on the Western Front and nearly 700,000 in the Middle East. 47,746 Indian soldiers were killed and 65,126 wounded during World War I.

, where they were finally defeated after a bitter fight. Amba Prasad Sufi was killed in this battle. The Ghadarites carried on guerrilla warfare along with the Iranian partisans till 1919.

Although the conflict in India was not explicitly a part of the First World War, it was part of the wider strategic context. The British attempt to subjugate the rebelling tribal leaders drew away much needed troops from other theaters, in particular, of course, the Western Front, where the real decisive victory would be made.

The reason why some Indian and Afghani tribes rose up simply came down to years of discontent which erupted, probably not coincidentally, during the First World War. It is likely that the tribal leaders were aware that Britain would not be able to field the required men, in terms of either number or quality, but underestimated the strategic importance of India to the British. Despite being far from the epicenter of the conflict, India provided a bounty of men for the fronts. Its produce was also needed for the British war effort and many trade routes running to other profitable areas of the Empire ran through India. Therefore, although the British were not able to send the men that they wanted, they were able to send enough to mount a gradual but effective counter-guerrilla war against the tribesmen. The fighting continued into 1919 and in some areas lasted even longer.

In December, the Central Powers signed an armistice with Russia. This released troops for use in the west. Ironically, German troop transfers could have been greater if their territorial acquisitions had not been so dramatic. With German reinforcements and new American troops pouring in, the final outcome was to be decided on the Western front. The Central Powers knew that they could not win a protracted war, but they held high hopes for a quick offensive. Furthermore, the leaders of the Central Powers and the Allies became increasingly fearful of social unrest and revolution in Europe. Thus, both sides urgently sought a decisive victory.

) to Mexico to join the war as Germany's ally against the United States, should the U.S. join. The proposal suggested, if the U.S. were to enter the war, Mexico should declare war against the United States and enlist Japan as an ally. This would prevent the United States from joining the Allies and deploying troops to Europe, and would give Germany more time for their unrestricted submarine warfare program to strangle Britain's vital war supplies. In return, the Germans would promise Mexico support in reclaiming Texas, New Mexico, and Arizona.

U.S. declaration of war on Germany

After the British revealed the telegram to the United States, President Wilson, who had won reelection on his keeping the country out of the war, released the captured telegram as a way of building support for U.S. entry into the war. He had previously claimed neutrality, while calling for the arming of U.S. merchant ships delivering munitions to combatant Britain and quietly supporting the British blockading of German ports and mining of international waters, preventing the shipment of food from America and elsewhere to combatant Germany. After submarines sank seven U.S. merchant ships and the publication of the Zimmerman telegram, Wilson called for war on Germany, which the U.S. Congress declared on 6 April 1917.

South of the French Third Army General Mangin (The Butcher) drove his French Tenth Army forward at Soissons on 20 August to capture eight thousand prisoners, two hundred guns and the Aisne heights overlooking and menacing the German position north of the Vesle. Another "Black day" as described by Ludendorff.

Meanwhile General Byng of the Third British Army, reporting that the enemy on his front was thinning in a limited withdrawal, was ordered to attack with 200 tanks toward Bapaume, opening what is known as the Battle of Albert with the specific orders of "To break the enemy's front, in order to outflank the enemies present battle front" (opposite the British Fourth Army at Amiens). Allied leaders had now realized that to continue an attack after resistance had hardened was a waste of lives and it was better to turn a line than to try and roll over it. Attacks were being undertaken in quick order to take advantage of the successful advances on the flanks and then broken off when that attack lost its initial impetus.

The British Third Army's front north of Albert progressed after stalling for a day against the main resistance line to which the enemy had withdrawn. Rawlinson’s Fourth British Army was able to battle its left flank forward between Albert and the Somme straightening the line between the advanced positions of the Third Army and the Amiens front which resulted in recapturing Albert at the same time. On 26 August the British First Army on the left of the Third Army was drawn into the battle extending it northward to beyond Arras.

Bapaume fell on the 29th to the New Zealand Division of the Third Army and the Australians, still leading the advance of the Fourth Army, were again able to push forward at Amiens to take Peronne and Mont St. Quentin on August 31. Further south the French First and Third Armies had slowly fought forward while the Tenth Army, who had by now crossed the Ailette and was east of the Chemin des Dames, was now near to the Alberich position of the Hindenburg line

 on the Canadian-First Army's front and back to a line east of the Lys in the north, giving up without a fight the salient seized in the previous April. According to Ludendorff “We had to admit the necessity…to withdraw the entire front from the Scarpe to the Vesle.”

In nearly four weeks of fighting since 8 August over 100,000 German prisoners were taken, 75,000 by the BEF and the rest by the French. Since "The Black Day of the German Army" the German High Command realized the war was lost and made attempts for a satisfactory end. The day after the battle Ludenforff told Colonel Mertz "We cannot win the war any more, but we must not lose it either." On 11 August he offered his resignation to the Kaiser, who refused it and replied, "I see that we must strike a balance. We have nearly reached the limit of our powers of resistance. The war must be ended." On 13 August at Spa, Hindenburg, Ludendorff, Chancellor and Foreign minister Hintz agreed that the war could not be ended militarily and on the following day the German Crown Council decided victory in the field was now most improbable. Austria and Hungary warned that they could only continue the war until December and Ludendorff recommended immediate peace negotiations, to which the Kaiser responded by instructing Hintz to seek the Queen of Holland's mediation. Prince Rupprecht warned Prince Max of Baden "Our military situation has deteriorated so rapidly that I no longer believe we can hold out over the winter; it is even possible that a catastrophe will come earlier." On 10 September Hindenburg urged peace moves to Emperor Charles of Austria and Germany appealed to Holland for mediation. On the 14th Austria sent a note to all belligerents and neutrals suggesting a meeting for peace talks on neutral soil and on 15 September Germany made a peace offer to Belgium. Both peace offers were rejected and on 24 September OHL informed the leaders in Berlin that armistice talks were inevitable.

September saw the Germans continuing to fight strong rear guard actions and launching numerous counter attacks on lost positions, with only a few succeeding and then only temporarily. Contested towns, villages, heights and trenches in the screening positions and outposts of the Hindenburg Line continued to fall to the Allies as well as thousands of prisoners, with the BEF alone taking 30,441 in the last week of September. Further small advances eastward would follow the Third Army victory at Ivincourt on 12 September, the Fourth Armies at Epheny on the 18th and the French gain of Essigny Le Grand a day later. On the 24th a final assault by both the British and French on a four mile (6 km) front would come within two miles (3 km) of St. Quentin. With the outposts and preliminary defensive lines of the Siegfried and Alberich Positions eliminated the Germans were now completely back in the Hindenburg line. With the Wotan position of that line already breached and the Siegfried position in danger of being turned from the north the time had now come for an assault on the whole length of the line.

 and closed on the Belgian frontier. The most significant advance came from Commonwealth units, as they entered Belgium. The last Belgian town to be liberated before the armistice was Ghent, which the Germans held as a pivot until Allied artillery was brought up. The German army had to shorten its front and use the Dutch frontier as an anchor to fight rear-guard actions.

By October, it was evident that Germany could no longer mount a successful defence. They were increasingly outnumbered, with few new recruits. Rations were cut. Ludendorff decided, on 1 October, that Germany had two ways out — total annihilation or an armistice. He recommended the latter at a summit of senior German officials. Allied pressure did not let up.

Allied superiority and the stab-in-the-back legend, November 1918
In November 1918 the Allies had ample supplies of men and materiel; continuation of the war would have meant the invasion of Germany. This had unforeseeable consequences; some Allied decision-makers felt the war should be "finished," not just stopped, and many voices on both sides voiced the opinion that the war was not really over. But most Allied decision-makers were eager to see the end of hostilities.

Berlin was almost from the Western Front; no Allied soldier had ever set foot on German soil in anger, and the Kaiser's armies retreated from the battlefield in good order. Thus many Germans, including Adolf Hitler

s. In the event of an enemy air attack, the crew could parachute to safety. At the time, parachutes were too heavy to be used by pilots of aircraft (with their marginal power output) and smaller versions would not be developed until the end of the war; they were also opposed by British leadership, who feared they might promote cowardice. Recognised for their value as observation platforms, balloons were important targets of enemy aircraft. To defend against air attack, they were heavily protected by antiaircraft guns and patrolled by friendly aircraft; to attack them, unusual weapons such as air-to-air rockets were even tried. Blimps and balloons contributed to air-to-air combat among aircraft, because of their reconnaissance value, and to the trench stalemate, because it was impossible to move large numbers of troops undetected. The Germans conducted air raids on England during 1915 and 1916 with airships, hoping to damage British morale and cause aircraft to be diverted from the front lines. The resulting panic took several squadrons of fighters from France.

Prisoners of war

About 8 million men surrendered and were held in POW camps during the war. All nations pledged to follow the Hague Convention on fair treatment of prisoners of war. In general, a POW's rate of survival was much higher than their peers at the front. Individual surrenders were uncommon. Large units usually surrendered en masse. At the Battle of Tannenberg

Over half of Russian losses were prisoners (as a proportion of those captured, wounded or killed); for Austria 32%, for Italy 26%, for France 12%, for Germany 9%; for Britain 7%. Prisoners from the Allied armies totalled about 1.4 million (not including Russia, which lost between 2.5 and 3.5 million men as prisoners.) From the Central Powers about 3.3 million men became prisoners.

Germany held 2.5 million prisoners; Russia held 2.9 million and Britain and France held about 720,000. Most were captured just prior to the Armistice. The U.S. held 48,000. The most dangerous moment was the act of surrender, when helpless soldiers were sometimes gunned down. Once prisoners reached a camp, in general, conditions were satisfactory (and much better than in World War II), thanks in part to the efforts of the International Red Cross and inspections by neutral nations. Conditions were terrible in Russia, starvation

One of the most dramatic effects of the war was the expansion of governmental powers and responsibilities in Britain, France, the United States, and the Dominions of the British Empire.

Macro- and micro-economic consequences devolved from the war. Families were altered by the departure of many men. With the death or absence of the primary wage earner, women were forced into the workforce in unprecedented numbers. At the same time, industry needed to replace the lost laborers sent to war.

), but not bread. The new system worked smoothly. From 1914 to 1918 trade union membership doubled, from a little over four million to a little over eight million. Work stoppages and strikes became frequent in 1917–18 as the unions expressed grievances regarding prices, alcohol control, pay disputes, fatigue from overtime and working on Sundays and inadequate housing. Conscription put into uniform nearly every physically fit man, six of ten million eligible. Of these, about 750,000 lost their lives and 1,700,000 were wounded. Most deaths were to young unmarried men; however, 160,000 wives lost husbands and 300,000 children lost fathers.

Cognate names for the war

Before World War II, the war was also known as The Great War, The World War, The War to End All Wars, The Kaiser's War, The War of the Nations and The War in Europe. In France and Belgium it was sometimes referred to as La Guerre du Droit (the War for Justice) or La Guerre Pour la Civilisation / de Oorlog tot de Beschaving (the War to Preserve Civilization), especially on medals and commemorative monuments.

The term used by official histories of the war in Britain and Canada is The First World War, while American histories generally use the term World War I.

'Ernst Heinrich Philipp August Haeckel' ,also written 'von Haeckel', was an eminent Germany biologist, natural history, philosopher, physician, professor and artist who discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms, and coined many terms in biology, including phylum, ph...
 used the key phrase shortly after the start of the fighting in Europe: "There is no doubt that the course and character of the feared "European War"...will become the first world war the full sense of the word."

Although the widespread use of the term First World War has been dated to 1931, the first known appearance of the phrase in print was in the Indianapolis Star's issue for 20 September 1914.

In many European countries, it appears the current usage is tending back to calling it The Great War / la Grande Guerre / de Grote Oorlog / der Große Krieg, because of the growing historical awareness that, of the two 20th century world wars, the 1914–1918 conflict caused more social, economic and political upheaval. It was also one of the prime factors in the outbreak of the Second World War.
