Izard's troops began steady, rolling volleys into the abatis and trees. These conventional tactics, better suited to pitched battles between regular forces in open terrain, were almost entirely ineffective against the Canadians. The defenders replied with accurate individual fire. Lieutenant Pinguet of the Canadian Fencibles later related "All our men fired from thirty-five to forty rounds so well aimed that the prisoners told us next day that every shot seem to pass at about the height of a man's breast or head. Our company was engaged for about three-quarters of an hour before reinforcements came up." Surprisingly few Americans were hit however. On the Canadian right, the light company of the Fencibles were outflanked and fell back, but either on de Salaberry's orders or on their own initiative, MacDonnell and several companies from the reserve were already making their way forward. They did so with bugle calls, cheers and Indian war whoops. De Salaberry is also credited in several accounts with sending buglers into the woods to sound the "Advance" as a ruse de guerre. The unnerved Americans thought themselves outnumbered and about to be outflanked and fell back . Hampton's four guns did not come into action.
