Final answer:
The Błonie concentration camp mentioned in the question seems to be an error, as Błonie was a location in Poland, not a camp. However, during WWII, the Soviet forces started liberating camps in July 1944, with Auschwitz being a notable example, while the Western Allies liberated others like Buchenwald and Dachau, providing food and medical aid to survivors.
Step-by-step explanation:
The question asks about the liberation of the Błonie concentration camp during World War II and what was provided to the survivors by the liberating Allied forces. There is a slight mistake in the question as Błonie was not a concentration camp but a location in Poland. The liberation of concentration camps across Europe was undertaken by various Allied forces as they advanced towards German-occupied territories. The Soviet armies started this process in July 1944 and liberated camps such as Auschwitz. The Western Allies, comprising principally of American and British troops, liberated other camps like Buchenwald, Bergen-Belsen, and Dachau. Survivors were provided with necessities, such as food supplies and medical care, and the brutal evidence discovered was documented thoroughly to be used in future war crimes trials.
