 were around 66,000 dead and 694,000 captured. Though the German attack was successful, losses were greater than expected. Because of this, Germany was forced to postpone war operations in the West until the spring of 1940 to replenish its losses. It has been estimated that, during the September campaign in Poland, the Wehrmacht needed to use more than twice the ammunition they used in France the following spring.

, the AK assisted the Soviet Union's war effort by sabotaging the German advance into Soviet territory and provided intelligence on the deployment and movement of German forces After 1943, its direct combat activity increased sharply. German losses to the Polish partisans averaged 850-1700 per month in early 1944 compared to about 250-320 per month in 1942.

In addition to the Home Army, there was an underground ultra-nationalist resistance force called Narodowe Siły Zbrojne (NSZ or National Armed Forces), with a fiercely anti-communist and chauvinist stance. It participated in fighting German units, winning many skirmishes. From 1943 onwards, some units took part in battling the Gwardia Ludowa

Other notable Polish resistance organizations included the Bataliony Chłopskie (BCh), a mostly peasant-based organization allied to the AK. At its height the BCh included 175,000 members.

On the other hand the role of the Polish Police force ('Granatowa Policja') in the illegal General Gouvernment ('Generalna Gubernia', a semi-state under the full control of Nazi Germany) remains a debatable issue. There was some co-operation between the Polish Police and the Nazis in persecuting the Jewish community while at the same time some officers secretly supported the underground resistance movement.

There were single instances of military and political co-operation between the Polish ultra-nationalist resistance movement and the Nazis ('Brygada Swietokrzyska', the attempts of professor Wladyslaw Studnicki etc.).
Throughout the war the German state was forced to divert a substantial part of its military forces to keep control over Poland:
