World War II

"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.)

In the summer of 1942, the Japanese were winning their war with the United States. They had sunk or crippled America's battleship fleet at Pearl Harbor, and snapped up a chain of islands across the Pacific which could, if fortified, form an impenetrable barrier to the U.S. Navy. Now the Imperial Japanese Navy was looking for a knockout blow, to destroy the American aircraft carriers before American industry replaced its losses.

After bouncing all night in cold, cramped steel boats, then waiting all day in broiling heat, the men of the Allied Expeditionary Force got the word: shortly after sundown, they would finally be getting off their floating, seasick prisons.

All they had to do then was run straight into machine gun fire, smash the Nazi army, and liberate Europe.
