This was the last episode of the Pigeon Hill affair, and in another week peace and quietness again prevailed along the Vermont border. CHAPTER XIV. FENIAN MOBILIZATION AT MALONE AND ELSEWHERE--GEN. MEADE'S PROMPT ACTION STOPS THE INVASION--ARREST OF GEN. SWEENY AND STAFF. The principal points of rendezvous for the Fenians who were intended to operate on the St. Lawrence frontier were Ogdensburg, Watertown, Malone and Potsdam, in the State of New York, and at these places large bodies of men began concentrating during the first two or three days in June. General Sweeny was in personal command of the troops of the Irish Republican Army in that department, and had made every arrangement to invade Canada along that line, in accordance with his original plan of campaign. He made his headquarters at Ogdensburg for a time, and from there directed the mobilization of his columns for the contemplated attacks on Prescott, Cornwall and other points on the Canadian border. Meanwhile Gen. Michael J. Heffernan, Gen. Murphy, and Gen. O'Reilly, were at Malone, N.Y., perfecting the military organization of the column which was intended to attack Cornwall. These officers were all old soldiers, who had held commands in the United States service during the Civil War, and were well posted in the business they had on hand. While the Fenian leaders were thus employed in getting their forces ready for the movement across the line, Major-General Geo. Meade (the commander of the United States troops) was equally active and vigilant in his determined efforts to stop the promised invasion. He ordered the seizure by the United States officials of all arms and ammunitions of war intended for use by the Fenians that could be located on American territory, and forbade the railways and other transportation companies from carrying further supplies of such material to the frontier. These orders were rigidly complied with, and seizures of arms and ammunition were made at Rouse's Point, Malone, Potsdam, Ogdensburg, Watertown, St. Albans and other places, which considerably disconcerted Gen. Sweeny's plans and thwarted his whole scheme. The presence of United States troops, which had been moved north from various military stations to support Gen. Meade in his efforts to prevent another breach of the Neutrality Act, also had a deterrent effect on the Fenians, and they became disheartened.
