The commander of the Army of the Potomac, Maj. Gen. George G. Meade, recommended Vincent for promotion to brigadier general on the evening of July 2. The promotion was dated July 3, 1863, but it is doubtful that Vincent knew about the honor before he died (although Pvt. Oliver Willcox Norton in "Army Letters 1861-1865" writes "His commission as Brigadier General was read to him on his deathbed.") Vincent's wife gave birth to a baby girl two months later, who died before reaching the age of one and is buried next to her father.
