Unused Waffen SS collar tab with lightning bolt insignia acquired by 22 year old Lt. Charles Rudulph, United States Army, during a July 10, 1945, visit to the former Dachau concentration camp near Munich in Germany. The tab would have been worn in a pair on the collar points of a uniform shirt or jacket. The SS (Schutzstaffel; Protection Squadrons) established Dachau, the first concentration camp in Nazi Germany, in March 1933. The SS commanded, administered, and guarded all concentration camps, and were known for their cruelty. Dachau was liberated by American forces on April 29, 1945. Rudulph, an officer in the 106th Infantry, entered combat in France in November 1944. He was wounded during the Battle of the Bulge but rejoined his unit. After Germany surrendered on May 7, he was posted to Straubing with Battery X, 566th AAA Battalion.
