Cotentin Peninsula
On 10 January 1944, Hellmich was moved to France and put in a command of the 243rd Infantry Division, a coastal defense division stationed in the Cotentin Peninsula. The division protected the western coast of the Cotentin Peninsula when Operation Overlord, the Allied invasion of Normandy, began on 6 June 1944. Hellmich was killed by 20-millimeter cannon shells during an Allied air attack on 17 June 1944.
