only by Native warriors, led by James Givins of the British Indian Department, and the grenadier company of the 8th Regiment of Foot, who were dispatched to the area by Sheaffe. Only the Natives initially engaged the American landing. With American cannon fire threatening the roads on the waterfront, the British units dispatched from Fort York had to traverse through the forest behind the waterfront; and were unable to reach the landing site before the Americans started their landings. Sheaffe had also ordered a company of the Glengarry Light Infantry to support the Natives at the landing, but they became lost in the outskirts of the town, having been misdirected by Major-General Aeneas Shaw, the Adjutant General of the Canadian Militia, who took some of the militia north onto Dundas Street to prevent any wide American flanking maneuver. After it became apparent that no landing would occur east of the settlement, Sheaffe recalled the companies of the 8th Regiment of Foot from the town's blockhouse. As the landings progressed, the British and Native force was outflanked and began to fall back into the woods. The U.S. 15th Infantry Regiment was the second American unit to land, with bayonets fixed, under a hail of fire, shortly followed by Pike, who assumed personal command of the landing. Sheaffe arrived with the rest of the 8th Regiment of Foot, the Royal Newfoundland Fencibles, and a few dozen militiamen after the U.S. 15th Infantry Regiment had landed. The grenadier company of the 8th Regiment of Foot charged them with the bayonet. The grenadiers were already outnumbered and were repulsed with heavy loss. Pike ordered an advance by platoons, supported by two 6-pounder field guns, which steadily drove back Sheaffe's force. After Sheaffe failed to get the Fencibles to renew their advance, the British began to withdraw, with the newly arrived Glengarry Light Infantry covering the retreat. During these landings, the American naval squadron bombarded the four gun batteries defending York. Chauncey's schooners, most of which carried a long 24-pounder or 32-pounder cannon, also bombarded the fort and Government House battery, with Chauncey himself directing them from a small boat. British return fire was ineffective. The British tried to rally around the Western battery, but the battery's travelling magazine (a portable chest containing cartridges) exploded, apparently as the result of an accident. This caused further loss (including 20 killed) and confusion among the British regulars,
