After university, Sobel was commissioned as an officer in the
Organized Reserve. By 1937, he had been promoted to
first lieutenant, and by July 1941, he had been ordered to active duty and assigned to
Camp Grant near
Rockford, Illinois. In 1942, Sobel was assigned to
Easy Company, 2nd Battalion,
506th Parachute Infantry Regiment as its initial member and commanding officer. Sobel commanded Easy Company during basic training at
Camp Toccoa,
Georgia, during which he was promoted to
captain. Sobel was intensely disliked by the men under his command, who saw him as a petty, arbitrary, domineering tyrant who handed down cruel punishments for the most minuscule of infractions, real or imagined. "Until I landed in France in the very early hours of
D-Day," recalled Corporal
Walter Gordon, "my war was with [Sobel]." Lieutenant
Richard Winters, Sobel's
executive officer, took exception to Sobel's "desire to lead by fear rather than example." The officers in Easy Company nicknamed Sobel "the Black Swan," and the enlisted men frequently referred to him as a "fucking Jew" when he was out of earshot. "I am going into combat with this man. He'll get us all killed," Winters recalled thinking. In 2009, Sergeant Amos "Buck" Taylor said: The situation escalated while the regiment was stationed in
Aldbourne, Wiltshire, England in October 1943. Sobel initiated
court-martial proceedings against Winters over Winters' failure to carry out conflicting
latrine inspection orders Sobel had given him. This caused the sentiment against Sobel to finally boil over: "Sobel had authority over the men [but] Lieutenant Winters had their respect. They were bound to clash,"
Stephen E. Ambrose wrote in
Band of Brothers. This conflict prompted all but three of the
non-commissioned officers in Easy Company to attempt to resign their ranks in protest. As a result, Colonel
Robert Sink, the regimental commander, set aside Winters' court-martial, and after furiously berating his NCOs for the attempted mutiny, replaced Sobel with Lieutenant Thomas Meehan as commander of Easy Company. Sink subsequently assigned Sobel to command an
airborne school in
Chilton Foliat, Wiltshire, which would provide jump training for non-combat personnel in preparation for the
invasion of France. By June 1944, Sobel and his staff had trained more than 400 men through the five practice jumps necessary to qualify as parachutists. On D-Day, Sobel parachuted into Normandy with the rest of the 101st Airborne Division as commander of the 506th's
service company. Immediately after landing, Sobel assembled four men and destroyed a German
machine gun nest with grenades before joining the rest of the division near
Carentan. Sobel spent the remainder of the war as a
staff officer in the 506th, and was appointed the regiment's
S-4 (
logistics officer) on March 8, 1945. ==Later life and death==
