With this command he thoroughly guarded, picketed and patrolled every important point east, west and north, and so keen was his vigilance that the enemy across the river could find no loop-hole for an attack and abandoned their intention.

The situation at Brockville was as grave as at other points along the frontier, owing to its close contiguity to the American shore.

It was the headquarters of the 42nd Battalion, which was speedily mustered under command of Lieut.-Col.

J.D.Buell.Several of the companies of this corps were located many miles from headquarters, but on receiving the call for active service they moved with remarkable activity, and arrived at the frontier within 24 hours after the summons had been sent forth.No.4 Company (Capt.

Allan Fraser), from Fitzroy, had about 80 miles to travel, partly by waggon and partly by rail.

They quickly mustered at Kinburn and moved with such celerity that they reported at Brockville early the next morning.
