It was just the style of fighting that suited the American troops. They wanted action, action every minute.  They wanted to see their enemies, to get at grips with them, to pit their brawn and muscle, their wit and courage against the best the enemy could bring forth.  It was the way their ancestors had fought, man to man, bayonet to bayonet, where sheer pluck and power would give the victory to the men who possessed them in largest measure.
