The President of the United States of America, in the name of Congress, takes pleasure in presenting the Medal of Honor to Captain (Cavalry) M. R. William Grebe, United States Army, for extraordinary heroism on 31 August 1864, while serving with Company F, 4th Missouri Cavalry, in action at Jonesboro, Georgia. While acting as aide and carrying orders across a most dangerous part of the battlefield, being hindered by a Confederate advance, Captain Grebe seized a rifle, took a place in the ranks and was conspicuous in repulsing the enemy.
