James H. Robinson was born in Oakland County Michigan in 1846. He enlisted as a private in the Union Army and served in Company B. 3rd Michigan Cavalry.

On August 25, 1863 at Brownsville Station, Arkansas, Confederate and Union cavalry forces skirmished in an attempt by the Confederate forces to prevent Union Army from proceeding toward Little Rock. This engagement was the first in a series which resulted in the capture of Little Rock on September 10, 1863 by the Union Army.

Robinson’s Medal of Honor citation read: "The President of the United States of America, in the name of Congress, takes pleasure in presenting the Medal of Honor to Private James H. Robinson for successfully defending himself, single-handed, against seven guerrillas, killing the leader (Captain W.C. Stephenson) and driving off the remainder of the party.

Robinson died on July 26, 1865 in Memphis, Tennessee and was buried in the Memphis National Cemetery.
