“LATER. About two hundred more Fenians reached the city at 10 o’clock, and left the train as the others did—some distance out of the city. They have just marched into town. A meeting is now being held in Townsend Hall, the Fenian head-quarters. The men are boarded at various Irish boarding houses. There is only a force of fifty regulars at Fort Porter here. Warning has been given, however, to the commander of the revenue steamer _Michigan_.” It was reported that the _Michigan_ had been about to leave Buffalo several days before on a cruise, but on rumours of an intended Fenian gathering at Buffalo reaching the United States authorities the commander had orders to remain. It was the presence of this vessel which now prevented the Fenians going at once to Port Colborne, terminus of the Welland canal twenty miles from Buffalo; at least this has been stated. During that day, Wednesday May 30, several rumours, not at any time probable gained currency; of which one was that trains had been arrested on the Great Western Railway, at Niagara Suspension Bridge.

COLONEL JOHN O’NEIL, of Nashville Tennessee, who was now at Buffalo and was on 31st of May, about to invade Canada, has been thus described in New York journals. “He is a young and ardent Fenian, and is now in his twenty-fifth year. He was formerly connected with the Sixteenth regiment of regulars, and served in that organization under Gen. Sweeny. He was well known as a dashing cavalry officer in the late war, when he was attached to a Western regiment. He was promoted to a captaincy for gallantry in a severe engagement.” A newspaper writer who conversed with O’Neil at Buffalo reported as follows:
