 When Braddock's regulars arrived in Alexandria, Washington spent much time there, observing infantry drills and other internal workings of the army, and even copied Braddock's orders to absorb the style in which they were written.The expedition finally marched off in April 1755, and made extremely slow progress along the road Washington had cut in 1754, owing to the heavy artillery and long baggage train.Braddock and his entourage arrived at Fort Cumberland on May 10.
