Squadron, and quickly became a flight leader. He was immediately resented by many of his fellow pilots, and the fact that he was opinionated and outspoken did little to ease the situation. In May, shortly after the group moved to RAF Halesworth and entered combat, Gabreski was promoted to major. On June 9, he took command of the 61st Fighter Squadron when its commanding officer was moved up to group deputy commander. This also stirred ill feelings toward him since he had been jumped over two more senior pilots. This ill-will was soon exacerbated when both of these men were lost in combat on June 26 and did not subside until he recorded his first credited kill: an Fw 190 near Dreux, France, on August 24, 1943. His first kill presaged criticism that followed him throughout his combat career, when his wingmen complained that his attack had been too hastily conducted to allow them to also engage. On November 26, 1943, the 56th FG was assigned to cover the withdrawal of Boeing B-17 Flying Fortress bombers that had bombed Bremen, Germany. The P-47s arrived to find the bombers under heavy attack near Oldenburg and dived into the fray. Gabreski recorded his fourth and fifth kills to become an ace, but had a close brush with death on December 11, when a 20 mm (.79 in) cannon shell lodged in his engine without exploding, destroying its turbocharger. Low on fuel and ammunition, Gabreski outmaneuvered a Bf 109 until it succeeded in placing a burst of fire into his P-47, disabling the engine. Gabreski stayed in the airplane, however, until it restarted at a lower altitude, where the turbocharger was not needed. In November 1943, the group commander of the 56th, Colonel Hubert Zemke, was replaced in command for two months by Colonel Robert Landry, a staff officer at VIII FC. Because of Landry's inexperience, combat missions of the 56th were alternately led by deputy commander Lieutenant Colonel David C. Schilling and Gabreski, who acted as deputy group operations officer. When Zemke resumed command on January 19, 1944, Gabreski relinquished command of the 61st FS. In February 1944, Gabreski brought two Polish pilots into the 56th, who had flown with him in 1943 while serving with the RAF, including future USAAF ace Squadron Leader Boleslaw "Mike" Gladych. With Gabreski's support and to ease a shortage of experienced pilots caused by many veterans
