Stalag I-A was a German prisoner-of-war camp located near the village of Stablack, about 8.5 km (5.3 mi) north-west of Preußisch Eylau, East Prussia (now Bagrationovsk in Russian Kaliningrad Oblast).
Located at coordinates 54 degrees 25 minutes North, 20 degrees 32 minutes 5 seconds east.
It was designed with a holding capacity of 10,000 only despite (as many) holding many more than this for most of its existence.
The camp was built in late 1939 by Polish prisoners of war. In 1940 the Poles were joined by Belgian and French prisoners, and by Russians in 1941. Some British and Italian prisoners were also there.
26047 Russians, 5411 Belgian, 4836 Polish, 731 Italians, 15794 French were held here including 163 officers according to reports given to SHAEF in February 1945.
However other reports show on 25th January 1945, as Russian troops approached, the camp was abandoned and all prisoners were evacuated to the west
