 Their helplessness in this situation gave rise to the nickname they would bear in the New York Times, "Grubb's Game Chickens".His younger brother, Parker Grubb, serving as the 37th New Jersey's regimental adjutant, died of disease during the regiment's service.In recognition of his service, on July 9, 1866, President Andrew Johnson nominated Grubb for appointment to the grade of brevet brigadier general of volunteers, to rank from March 13, 1865, for "gallant and meritorious services during the war" and the United States Senate confirmed the appointment on July 23, 1866.
