Shortly before 12 o'clock (noon). General Foster, the United States Marshal for the Northern District of Vermont, drove over to the Canadian lines and had an interview with Lieut.-Col. Chamberlin. He said that he desired to offer assurances that his Government and himself personally were doing all that was possible to prevent a raid, and that the United States troops were being moved up to assist him in the discharge of his duty and enforcement of the neutrality laws as fast as they could be transported. He also stated that he was charged with a message from Gen. O'Neil, to say that those under his command would not make war upon women or children, nor be permitted to plunder peaceable inhabitants, but would conduct their war in the manner approved among civilized nations. Col. Chamberlin replied that he would receive no message from men who were mere pirates and marauders, and it was scarcely satisfactory to those whom they intended to murder, because they were in arms for the defence of their Government and country, that their piracy would not be attended with unusual barbarities. While they were still in conversation, the head of the Fenian column began to advance. Lieut.-Col. Chamberlin called Gen. Foster's attention to the fact, who replied, "I thought they intended to attack you soon, but not so soon as this." He then drove away in the direction of and past the advancing Fenian column. Lieut.-Col. Chamberlin then hastily made such disposition of his small force as seemed most advantageous, with Capt. Bockus on the left of the skirmish line, which rested on the main road. The enemy advanced in close column, about 200 strong, with an advance guard about 100 yards ahead of the main body. On its approach to the boundary line it was ordered to move at the double, and the advance guard rushed across. As soon as it was on Canadian soil, Lieut.-Col. Chamberlin's men opened fire on the advance guard. The fire was returned from the main column of attack, which was still within United States territory. The conflict then became general. Upon the first volley from the Canadians one man in the leading section of the Fenian advance guard was shot dead and others wounded. The remaining men comprising it then sought refuge behind the neighboring barns and under a bridge near at hand. The main body halted, wavered, partially rallied again, and then, being galled by the well-directed fire of the Canadians, broke and ran for cover behind the houses and stone fences along the road, or made their way to a wood which crowned the summit of the hill opposite to our position on the western side of the road, another man being killed and several more wounded while seeking this shelter. From this time a desultory fire was kept up from behind trees and fences.
