At the time of the invasion of Canada in 1812, the garrison of York was manned by the 3rd regiment of York militia. We have before us a relic of the period, in the form of the contemporary regimental order-book of the Fort. An entry of the 29th of July, 1812, showing the approach of serious work, has an especial local interest. "In consequence of an order from Major-General Brock, commanding the forces, for a detachment of volunteers, under the command of Major Allan, to hold themselves in readiness to proceed in batteaux from the Head of the Lake to-morrow at 2 o'clock, the following officers, non-commissioned officers and privates will hold themselves in readiness to proceed at 2 o'clock, for the purpose of being fitted with caps, blankets and haversacks, as well as to draw provisions. On their arrival at the Head of the Lake, regimental coats and canteens will be ready to be issued to them." The names are then given. "Capt. Heward, Lieut. Richardson, Lieut. Jarvis, Lieut. Robinson. Sergeants Knott, Humberstone, Bond, Bridgeford." In view of the test to which the citizen-soldiers were about to be subjected, the General, like a good officer, sought by judicious praise, to inspire them with self-confidence. "Major-General Brock," the order-book proceeds, "has desired me (Captain Stephen Heward) to acquaint the detachment under my command, of his high approbation of their orderly conduct and good discipline while under arms: that their exercise and marching far exceeded any that he had seen in the Province. And in particular he directed me to acquaint the officers how much he is pleased with their appearance in uniform and their perfect knowledge of their duty." On the 13th of August, we learn from other sources, Brock was on the Western Frontier with 700 soldiers, including the volunteers from York, and 600 Indians; and on the 16th the old flag was waving from the fortress of Detroit; but, on the 13th October, the brave General, though again a victor in the engagement, was himself a lifeless corpse on the slopes above Queenston; and, in April of the following year, York, as we have already seen, was in the hands of the enemy. Such are the ups and downs of war. It is mentioned that "Push on the York Volunteers!" was the order issuing from the lips of the General, at the moment of the fatal shot. From the order-book referred to, we learn that "Toronto" was the parole or countersign of the garrison on the 23rd July, 1812. The knoll on the east side of the Garrison Creek was covered with a number of buildings for the accommodation of troops, in addition to the barracks within the fort. Here also stood a block-house. Eastward were the surgeon's quarters, overhanging the bay; and further eastward still, were the commandant's quarters, a structure popularly known, by some freak of military language, as Lambeth Palace. Here for a time resided Major-General Æneas Shaw, afterwards the owner and occupant of Oak Hill.
