World War II
During World War II, Ginder was the assistant chief of staff for personnel (G-1) for the Fourth United States Army. Appointed to command the 357th Infantry Regiment, a unit of the 90th Infantry Division, he was among the first ashore during the Normandy landings on D-Day, June 6, 1944. Ginder developed a reputation for subpar performance in combat, with observers and subordinates calling him "obtuse" and "full of boast and posturing." 357th veteran William E. DePuy called Ginder "as close to being incompetent as it is possible to be." Ginder was ultimately relieved of command during combat and escorted to the division command post under armed guard.
He was in command of the 9th Infantry Regiment when it captured the German town of Hürtgen as part of the Battle of Hürtgen Forest. It was for this action that he received the Distinguished Service Cross for actions on November 28, 1944, when he personally led his reserve company through the town in bitter house-to-house fighting while armed only with his pistol and a hand grenade. The citation for the DSC reads:
The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to Colonel (Infantry) Philip DeWitt Ginder, United States Army, for extraordinary heroism in connection with military operations against an armed enemy while Commanding an Infantry Company of the 121st Infantry Regiment, 8th Infantry Division, in action against enemy forces on 28 November 1944, in Germany. Colonel Ginder personally led his reserve company of his battalion in an attack against a strongly defended town, when other attacking companies were pinned down by intense enemy small arms and mortar fire. With complete disregard for his own personal safety and armed only with his pistol and a hand grenade, Colonel Ginder courageously moved forward leading his men into the town despite the fierce enemy resistance. During the bitter house-to-house fighting that followed, Colonel Ginder through his personal courage and leadership, set an inspiring example which gave added encouragement to his men. Colonel Ginder's courageous actions, personal bravery and zealous devotion to duty exemplify the highest traditions of the military forces of the United States and reflect great credit upon himself, the 8th Infantry Division, and the United States Army.
Ginder was appointed the commanding officer of the 9th Infantry Regiment in the spring of the 1945, replacing Chester Hirschfelder. Ginder commanded the regiment until the end of the war, taking part in liberating the western part of Czechoslovakia, and ending the war in the town of Rokycany near Pilsen.
In addition to his DSC, Ginder was also awarded the Silver Star, "for conspicuous gallantry and intrepidity in connection with military operations against the enemy", and the Legion of Merit, "for exceptionally meritorious conduct in the performance of outstanding services to the Government of the United States" for his service during the war.
