Civil War Union Army Officer. He served during the Civil War as a 1st Lieutenant in the 1st Ohio Independent Light Battery. At the September 14, 1862 Battle of South Mountain, Maryland, he commanded a section of two ten-pound Parrott guns that were deployed at the top of South Mountain in support of troops of the Kanawha Division. Under heavy riflery from North Carolina Confederate troops, his section managed to get off four rounds while men were being shot. When all of the men manning one gun went down wounded, Lieutenant Crome and a volunteer from the 12th Ohio Infantry manned it themselves. After firing off one last round, Lieutenant Crome was shot in the breast, and fell mortally wounded. He died two hours later. In his official report, Battery commander Captain James R. McMullin eulogized Lieutenant Crome, stating "His loss is to be deeply regretted, for he was a brave and noble man, who at the first call of this country left the endearments of home for its defense. Yet it is a consolation to his friends and companions in arms to know that he died at his post in the discharge of more than his duty".
