The earliest Gallo-Belgic coins found in Britain were struck in Gaul and are dateable to before 100 BC, perhaps as early as 150 BC, and are found mainly in Kent. Later coins of a similar type were struck in Britain and are found all along the south coast as far west as Dorset. It appears that Belgic settlement was concentrated on the south-east coast, although their influence spread further west and inland, perhaps through chieftains establishing political control over the native population.

In late summer, 55 BC, even though it was late in the campaigning season, Caesar decided to make an expedition to Britain. He summoned merchants who traded with the island, but they were unable or unwilling to give him any useful information about the inhabitants and their military tactics, or about harbours he could use, presumably not wanting to lose their monopoly on cross-channel trade.

Clearly in a hurry, Caesar himself left a garrison at the port and set out "at the third watch" - about midnight - on 23 August with the legions, leaving the cavalry to march to their ships, embark, and join him as soon as possible. In light of later events, this was either a tactical mistake or (along with the fact that the legions came over without baggage or heavy siege gear) confirms the invasion was not intended for complete conquest.

Landing

Caesar initially tried to land at Dubris
Dubris

Dubris or Portus Dubris was a town in Roman Britain. It is now Dover, Kent, England.As the closest point to continental Europe and the site of the estuary of the River Dour, Kent, the site chosen for Dover was ideal for a cross-channel port....
 (Dover

), whose natural harbour had presumably been identified by Volusenus as a suitable landing place. However, when he came in sight of shore, the massed forces of the Britons gathered on the overlooking hills and cliffs (i.e. the White cliffs of Dover

The white cliffs of Dover are cliffs which form part of the Great Britain coastline facing the Strait of Dover and France. The cliffs are part of the North Downs formation....
) dissuaded him from landing there, since the cliffs were "so close to the shore that javelins could be thrown down from" them onto anyone landing there. After waiting there at anchor "until the ninth hour" (about 3pm - presumably waiting the wind and tide to become favourable) and meanwhile convening a council of war, he ordered his subordinates to act on their own initiative and then sailed the fleet about seven miles along the coast to an open beach. In the absence of archaeological evidence at the landing point, this beach was most probably at Walmer

 - but is now thought to be half a mile further south, where it is now marked by a concrete memorial.

Having been tracked all the way along the coast by the British cavalry and chariots, the landing was opposed. To make matters worse, the Roman ships were too large to go close inshore and the troops had to disembark in deep water, all the while attacked by the enemy from the shallows. The troops were reluctant, but according to Caesar's account were led by the aquilifer
Aquilifer

 (standard bearer) of the 10th legion who jumped in first as an example, shouting:

"Leap, fellow soldiers, unless you wish to betray your eagle to the enemy. I, for my part, will perform my duty to the republic and to my general."


The British were eventually driven back with catapultae

 and slings fired from the warships into the exposed flank of their formation and the Romans managed to land and drive them off. The cavalry, delayed by adverse winds, still had not arrived, so the Britons could not be pursued and finished off, and Caesar could not enjoy what he calls, in his usual self-promoting style, his "accustomed success".

Beach-head

The Romans established a camp (of which no archaeological trace has been found - otherwise the landing point could be placed with certainty), received ambassadors and had Commius, who had been arrested as soon as he had arrived in Britain, returned to him. Caesar claims he was negotiating from a position of strength and that the British leaders, blaming their attacks on him on the common people, were in only four days awed into giving hostages (some immediately, some as soon as they could be brought from inland) and disbanding their army. However, after his cavalry had come within sight of the beachhead but then been scattered and turned back to Gaul by storms, and with food running short, Caesar, a native of the non-tidal Mediterranean

, was taken by surprise by the British tides. At high tide, his beached warships filled with water, and his transports, riding at anchor, were driven against each other. Some ships were wrecked, and many others were rendered unseaworthy by the loss of rigging or other vital equipment, threatening the return journey. Realising this and hoping to keep Caesar in Britain over the winter and thus starve him into submission, the Britons renewed the attack, ambushing one of the legions as it foraged

 near the Roman camp. The foraging party was relieved by the remainder of the Roman force and the Britons were again driven off, only to regroup after several days of storms with a larger force to attack the Roman camp. This attack was driven off fully, in a bloody rout, with improvised cavalry that Commius had gathered from pro-Roman Britons and a Roman scorched earth

 policy.

Conclusion

The British once again sent ambassadors and Caesar, although he doubled the number of hostages, realised he could not hold out any longer and dare not risk a stormy winter crossing (he had set out late in the campaigning season and the winter solstice
Solstice

 was approaching), and so allowed them to be delivered to him in Gaul, to which he returned with as many of the ships as could be repaired with flotsam from the wrecked ships. Even then, only two tribes felt sufficiently threatened by Caesar to actually send the hostages, and two of his transports were separated from the main body and made landfall elsewhere.

Success and motivation

In short, the campaign had not been a success. If it had been intended as a full-scale campaign, invasion or occupation, it had failed, and even if it is seen as a reconnaissance-in-force or a show of strength to deter further British aid to the Gauls, it had fallen short. Nonetheless, going to Britain at all carried such kudos for a Roman that the Senate

Caesar's pretext for the invasion was that "in almost all the wars with the Gauls succors had been furnished to our enemy from that country". This is plausible, although it may also have been a cover for investigating Britain's mineral resources and economic potential: afterwards, Cicero

 and his brother Quintus
Quintus Tullius Cicero

Quintus Tullius Cicero was the younger brother of the celebrated orator, philosopher and statesman Marcus Tullius Cicero. He was born in 102 BC into a family of the equestrian order, as the eldest son of a wealthy landowner in Arpino, some 100 kilometres south-east of Rome....
, both of whom were serving in Caesar's army, expressing his excitement at the prospect. He urged Trebatius to capture him a war chariot, and asked Quintus to write him a description of the island. Trebatius, as it turned out, did not go to Britain, but Quintus did, and wrote him several letters from there - as did Caesar himself.

Determined not to make the same mistakes as the previous year, Caesar gathered a larger force than on his previous expedition (five legions as opposed to two, plus cavalry), carried in ships which he designed, with experience of Venetic shipbuilding technology, to be more suitable to a beach landing than those used in 55 BC (i.e. broader and lower for easier beaching). This time he names Portus Itius as the departure point.

Crossing and landing

Labienus was left at Portus Itius to oversee regular food transports from there to the British beachhead. The military ships were joined by a flotilla of trading ships captained by Romans and provincials from across the empire, and local Gauls, hoping to cash in on the trading opportunities. It seems more likely that the figure Caesar quotes for the fleet (800 ships) include these traders and the troop-transports, rather than the troop-transports alone.

Caesar landed at the place he had identified as the best landing-place the previous year. The Britons did not oppose the landing, apparently, as Caesar states, intimidated by the size of the fleet, but equally this may have been a strategic ploy to give them time to gather their forces, or may reflect their lack of concern.

Kent campaign

Upon landing, Caesar left Quintus Atrius
Quintus Atrius

Quintus Atrius was a Roman Republic military officer involved in Julius Caesar's second Caesar's invasions of Britain in 55 BC. He was left in charge of ten Cohort of infantry and 300 cavalry to guard the beach-head while Caesar began his march inland, but halted his commander's advance by sending him word that his ships had been damaged by...

). The Britons attacked but were repulsed, and attempted to regroup at a fortified place in the forests (possibly to be identified with the hillfort at Bigbury Wood, Kent,) but were again defeated and scattered. As it was late in the day and Caesar was unsure of the territory, he called off the pursuit and made camp.

However, the next morning, as he prepared to advance further, Caesar received word from Atrius that, once again, his ships at anchor had been dashed against each other in a storm and suffered considerable damage. About forty, he says, were lost. The Romans were unused to Atlantic and Channel

 tides and storms, but nevertheless, considering the damage he had sustained the previous year, this was poor planning on Caesar's part. However, Caesar may have exaggerated the number of ships wrecked to magnify his own achievement in rescuing the situation. He returned to the coast, recalling the legions that had gone ahead, and immediately set about repairing his fleet. His men worked day and night for approximately ten days, beaching and repairing the ships, and building a fortified camp around them. Word was sent to Labienus to send more ships.

Discoveries about Britain

As well as noting elements of British warfare (particularly the use of chariots) which were exotic and unfamiliar to his Roman audience, Caesar also aimed to impress them by making further geographical, meteorological and ethnographic investigations of Britain. He probably gained these by enquiry and hearsay rather than direct experience, as he did not penetrate that far into the interior, and most historians would be wary of applying them beyond the tribes with whom he came into direct contact.

Geographical and meteorological

Caesar's first-hand discoveries were limited to east Kent and the Thames Valley, but he was able to provide a description of the island's geography and meteorology. Though his measurements are not wholly accurate, and may owe something to Pytheas, his general conclusions even now hold water:

The climate is more temperate than in Gaul, the colds being less severe.


The island is triangular in its form, and one of its sides is opposite to Gaul. One angle of this side, which is in Kent, whither almost all ships from Gaul are directed, [looks] to the east; the lower looks to the south. This side extends about 500 miles. Another side lies toward Spain and the west, on which part is Ireland, less, as is reckoned, than Britain, by one half: but the passage from it into Britain is of equal distance with that from Gaul. In the middle of this voyage, is an island, which is called Mona
Anglesey

Anglesey is an island and principal areas of Wales off the northwest coast of Wales, with a predominantly Welsh language-speaking population. It is connected to the mainland by two bridges spanning the Menai Strait: the original Menai Suspension Bridge , designed by Thomas Telford in 1826; and the newer reconstructed Britannia Bridge ; which...
: many smaller islands besides are supposed to lie there, of which islands some have written that at the time of the winter solstice it is night there for thirty consecutive days. We, in our inquiries about that matter, ascertained nothing, except that, by accurate measurements with water, we perceived the nights to be shorter there than on the continent. The length of this side, as their account states, is 700 miles. The third side is toward the north, to which portion of the island no land is opposite; but an angle of that side looks principally toward Germany. This side is considered to be 800 miles in length. Thus the whole island is about 2,000 miles in circumference.


No information about harbours or other landing-places was available to the Romans before Caesar's expeditions, so Caesar was able to make discoveries of benefit to Roman military and trading interests. Volusenus's reconnaissance voyage before the first expedition apparently identified the natural harbour at Dubris

By Claudius's time Roman knowledge of the island would have been considerably increased by a century of trade and diplomacy, and four abortive invasion attempts. However, it is likely that the intelligence gathered in 55 and 54 BC would have been retained in the now-lost state records in Rome, and been used by Claudius in the planning of his landings.

Ethnography

The Britons are defined as typical barbarian

s, with polygamy and other exotic social habits, similar in many ways to the Gauls, yet as brave adversaries whose crushing can bring glory to a Roman:

The interior portion of Britain is inhabited by those of whom they say that it is handed down by tradition that they were born in the island itself: the maritime portion by those who had passed over from the country of the Belgae for the purpose of plunder and making war; almost all of whom are called by the names of those states from which being sprung they went thither, and having waged war, continued there and began to cultivate the lands. The number of the people is countless, and their buildings exceedingly numerous, for the most part very like those of the Gauls... They do not regard it lawful to eat the hare, and the cock, and the goose; they, however, breed them for amusement and pleasure.


The most civilized of all these nations are they who inhabit Kent

, which occasions a bluish colour, and thereby have a more terrible appearance in fight. They wear their hair long, and have every part of their body shaved except their head and upper lip. Ten and even twelve have wives common to them, and particularly brothers among brothers, and parents among their children; but if there be any issue by these wives, they are reputed to be the children of those by whom respectively each was first espoused when a virgin.


Military

In addition to infantry and cavalry, the Britons employed chariots, a novelty to the Romans, in warfare. Caesar describes their use as follows:

Their mode of fighting with their chariots is this: firstly, they drive about in all directions and throw their weapons and generally break the ranks of the enemy with the very dread of their horses and the noise of their wheels; and when they have worked themselves in between the troops of horse, leap from their chariots and engage on foot. The charioteers in the mean time withdraw some little distance from the battle, and so place themselves with the chariots that, if their masters are overpowered by the number of the enemy, they may have a ready retreat to their own troops. Thus they display in battle the speed of horse, [together with] the firmness of infantry; and by daily practice and exercise attain to such expertness that they are accustomed, even on a declining and steep place, to check their horses at full speed, and manage and turn them in an instant and run along the pole, and stand on the yoke, and thence betake themselves with the greatest celerity to their chariots again.

Religion

"The institution [of Druidism] is thought to have originated in Britain, and to have been thence introduced into Gaul; and even now those who wish to become more accurately acquainted with it, generally repair thither, for the sake of learning it."


Economic resources

Caesar not only investigates this for the sake of it, but also to justify Britain as a rich source of tribute and trade:

[T]he number of cattle is great. They use either brass or iron rings, determined at a certain weight, as their money. Tin is produced in the midland regions; in the maritime, iron; but the quantity of it is small: they employ brass, which is imported. There, as in Gaul, is timber of every description, except beech and fir.
