MAY 4, 1945

The 71st Infantry 'Red Circle' Division liberated Gunskirchen, one of the many subcamps of the Mauthausen concentration camp in Austria.

Construction of the Gunskirchen camp began in December 1944. The camp was planned to house several hundred slave laborers. When the camp was opened in April 1945, however, thousands of prisoners evacuated on death marches from Mauthausen started to flood Gunskirchen. In these overcrowded conditions, diseases such as typhus and dysentery spread rapidly through the starving and weakened camp population. The prisoners were—with the exception of 400 political prisoners—Jews from Hungary whom the Germans had forced to march on foot from their homeland to Austria, where they were to be used for forced labor. Some 17,000 Hungarian Jews reportedly passed through the Gunskirchen camp.

When troops of the 71st entered the camp, they learned that the SS guards had fled the corpse-littered camp days before. Some 15,000 prisoners were still in the camp. In the months following the liberation, some 1,500 former prisoners died as a consequence of their mistreatment by the Nazis.

Liberator Division: For their part in liberating these camps, the 71^st Infantry Division was accorded “liberator” status in 1985 by a joint program of the U.S. Holocaust Memorial Museum and the U.S. Army Center of Military History, which was an effort on the part of these two entities to recognize U.S. Army units that took part in freeing prisoners from Nazi concentration camps.

The text on the brass plaque is written in English and German.  The English reads:
