Lieut.-Col. W. Osborne Smith, D.A.G., had command of the troops which were assembled on the Huntingdon and Hemmingford frontiers, which consisted of the 1st Prince of Wales Rifles (Lieut.-Col. B. Devlin), of Montreal; the Victoria Rifles, of Montreal; one division of Capt. A. A. Stevenson's Field Battery, of Montreal; the Hemmingford. Roxham and Havelock Infantry Companies, and a detachment of the Montreal Cavalry. With this force he proceeded to Hemmingford, where he halted on the 3rd and sent out scouts to observe the operations of the enemy on the frontier. Learning that an attack was likely to be made on the Huntingdon frontier. Col. Smith left next morning at daybreak with his column for the threatened point. The weather was exceedingly unfavorable, as it rained incessantly all day, and the roads were in a very bad state. Still he pushed on, and covered 37 miles, which his troops accomplished in a splendid manner, and went into camp that night with only two patients reported on the hospital returns as being incapacitated by the fatiguing march. The direct approach to Huntingdon from Malone, where the Fenians were mobilizing, is by the Trout River Road, and across this path Col. Smith constructed a line of breastworks and awaited the approach of the enemy. His position was admirably chosen, and had Gen. Sweeny made an advance down the Chateauguay Valley, he would have met with such a stout resistance that his defeat would have been certain, as the Canadian position was impregnable. For a few days all kinds of rumors were current of an advance being made by the Fenians, and constant vigilance was maintained, but the attack failed to eventuate. Lieut.-Col. George Browne, D.A.G., with the 1st and 2nd Huntingdon Infantry Companies; the Athelstan, Durham and Rockburn Infantry Companies, and the Hinchinbrooke Rifle Company, also assisted to hold the Huntingdon line, and did good service in keeping guard on the frontier. With the salient points along the Canadian border being thus securely guarded, and every soldier on the _qui vive_, the Fenian troops would most certainly have encountered very strong opposition before they could carry out their designs to conquer Canada.
