LIEUT.-COL. BOOKER’S REPORT OF THE COMBAT AT LIMESTONE RIDGE. PORT COLBORNE, June 2, 1866. SIR,—I have the honour to report that, in accordance with instructions received from Colonel Peacocke, through Capt. Akers, I proceeded by train at 5 a. m. to-day to Ridgway station on the Buffalo and Lake Huron R. R., with the Queen’s Own, of Toronto, Major Gilmore, say 480 men of all ranks; the York Rifles, Capt. Davis; the Caledonia Rifles, Capt. Jackson; and the 13th Battalion of Hamilton—together about 360 men—total of all ranks, say 840 men, in order to form a junction with Col. Peacocke, at Stevensville, at 9 to 9.30 a. m. On arriving at Ridgway, I sent the Great Western Railway train away; and as I could not obtain a horse or waggon in the place for the conveyance of the force, I was compelled to leave without the stores, and sent them back to Port Colborne at a little before 8 a. m. We were feeling our way on the Stevensville road, and were about three miles from that village, when our advanced guard felt the enemy—Major Gilmore extended the Queen’s Own in skirmishing order, in admirable style—the men advancing in good spirits. They were supported and relieved, as required, by the 13th Battalion of Hamilton and the Rifle companies from York and Caledonia. After Major Gilmore had expended much ammunition, he reported to me that his ammunition was failing. At 9.30, after being engaged under a hot fire for an hour and a half, I observed the enemy throwing back his right and reinforcing his left flank. I immediately ordered up two companies in support, to counteract the movement. At this moment I received a telegram by the hands of Mr. Stovin, Welland Railway, on the field, informing me that Col. Peacocke could not leave Chippewa before 7 o’clock, instead of 5 a. m., the hour named by Capt. Akers on his behalf. The enemy was strongly posted in the woods on the west of the garrison road, the road forming the entrance as it were to a _cul de sac_. We outflanked him, when he brought up his centre reserves and outflanked us. We drove them, in the first place, over a mile, and held possession of the rifle pits. A cry of cavalry from the front, and the retreat of a number of men in our centre on the reserves, caused me to form a square and prepare for cavalry. This mistake originated from relieved skirmishers doubling back. I immediately re-formed column, and endeavoured to deploy to the right. A panic here seized our men, and I could not bring them again to the front. I regret to say we have lost several valuable officers and men. I estimate the strength of the enemy as greater than ours; and, from the rapid firing, they were evidently armed with repeating rifles.
