We are now arrived at the morning of June 2nd. In the Niagara District the first act of the Fenian Invasion being in progress Colonel Peacocke is looked to as the leading actor in the operations. Around him the main forces for defence and repulsion of the enemy have gathered. On him expectation rests. A senior officer Colonel Lowry of the 47th will presently appear, but not yet. Colonel Peacocke’s official report as written in his own terms is demanded by the pretentions of this narrative to fulness, and fidelity to truth. A chapter describing his advance and halts from Suspension Bridge to Fort Erie to be followed by that report, and the report by comments on his movements and strategy would occupy too many of these pages. It is convenient therefore to introduce his official statement first. This is it: COLONEL PEACOCKE’S REPORT; _To Major-General G. Napier, C. B. Commanding 1st Military District, Toronto, C. W._ FORT ERIE, 4th June, 1866. SIR.—I have the honor to make the following Report of my operations in the field since the 1st inst. In compliance with a telegram received from you, I joined at 2 o’clock, at Hamilton, with 200 men of my own battalion, the force proceeding from Toronto to St. Catherines, consisting of one battery of Royal Artillery, under the Command of Lieut.-Col. Hoste, C. B., and 200 men of the 47th Regt, under the command of Major Lodder. You had also placed under my command, for the defence of the frontier, 7 companies of the volunteer force stationed at St. Catherines, under the command of Lieut.-Col. Currie, the Queen’s Own regiment of volunteers at Port Colborne, and the 13th Battalion volunteer militia, commanded by Lieut.-Col. Booker, at Dunnville; and you had informed me that I should be reinforced at St. Catherines by 800 men. Your instructions were that I was to make St. Catherines my base, to act according to my own discretion, to advance on Clifton or elsewhere, and to attack the enemy as soon as I could do so with a force sufficient to ensure success. On arriving at St. Catherines, I received telegrams to the effect that the Fenians, about 800 strong, were marching on the Suspension Bridge and were actually two or three miles from Chippewa. I pushed on immediately to the Bridge, leaving orders for all troops arriving at St. Catherines to follow me as soon as possible. On reaching the Bridge, I heard that the enemy had not yet reached Chippewa, and being anxious to save the bridge over the creek, I pressed on with the 400 infantry, preceded by a pilot engine—the battery marching by road in consequence of the reported want of platform accommodation at the Chippewa station.
