Elmer E. Ellsworth, American colonel (b. 1837)
Elmer Ephraim Ellsworth (April 11, 1837 – May 24, 1861) was a United States Army officer and law clerk who was the first conspicuous casualty and the first Union officer to die in the American Civil War. He was killed while removing a Confederate flag from the roof of the Marshall House inn in Alexandria, Virginia.Before the war, Ellsworth led a touring military drill team, the "Zouave Cadets of Chicago". He was a close personal friend of Abraham Lincoln, who as President later eulogized him as "the greatest little man I ever met". After his death, Ellsworth's body lay in state at the White House. The phrase, "Remember Ellsworth", became a rallying cry and call to arms for the Union Army.
