He is memorialized at the Sicily-Rome American Cemetery, Nettuno, Italy.
Aircraft C-47A with serial number 42-23506 departed from Enfidaville, Field No. 1 on a night paratroop drop to the drop zone near Gola in Sicily. His unit participated in operation Husky II in Sicily, dropping paratroopers of the 82nd Airborne Division. The airplane accidentally was hit by friendly fire and naval A/A guns and exploded. He was never recovered.
Eyewitness account by Captain Edwin L. Hibner:
I last saw 506 piloted by Major Dekker and Captain Dobbins heading along the coast northeast from Gela, just off shore. At this time (approximately 2113 GMT) the plane flew through a barrage of anti-aircraft fire, both from the ground and from naval vessels, at which time I lost sight of it and proceeded home. The guns are believed to be friendly because they were located at points known to be in our possession, and also because in some cases they ceased firing when the recognition signal was flashed.
