World War I
Memorial Day has a long history, reaching back to the end of the Civil War. On April 9, 1865, Robert E. Lee surrendered his army, and soldiers of the North and South went home to their families, their ranks thinned by the war's bloodshed. Thousands upon thousands of the men who went to battle never returned. At home, their families grieved for the fathers and brothers lost to them and looked for a way to memorialize their sacrifices.
"That two battalions of Marines be raised consisting of one colonel, two lieutenant colonels, two majors and officers as usual in other regiments, that they consist of an equal number of privates with other battalions; that particular care be taken that no person be appointed to office or enlisted into said battalions, but such as are good seamen, or so acquainted with maritime affairs as to be able to serve to advantage by sea."
(Resolution of the Continental Congress, 10 November 1775.)
