Stalag XX-A was a German World War II prisoner-of-war camp located in Toruń in German-occupied Poland.

[4] The Polish resistance movement facilitated escapes of British POWs from the camp, subsequently sheltering them in Bydgoszcz, and transporting them through Gdynia to neutral Sweden.

In accordance with the Third Geneva Convention, POWs below the rank of Sergeant were required to work and were attached to Arbeitskommando ("labour units") mostly located in various towns and villages in the region.

According to the International Red Cross and British POW Sam Kydd living conditions in the sub-camps were much better than in the main camp.

During his internment, where he remained for the next five years, he took command of the camp's theatrical activities - devising and staging plays.

While imprisoned in a sub-camp in Wyrzysk, Sam Kydd had contact with local Poles and learned various phrases in Polish.
