He fought with fixed prolonge until the enemy were within six feet of him, and then retired with the loss of three officers and twenty-eight men.

The artillery, by using the prolonge, may also continue its retreat while in battery and firing.

"Retire by prolonge!" he shouted to the battery commander, pulling in his sweating horse.
