The Ice Blockade at Louisburg.

Shirley had directed Pepperell to destroy St. Peter’s. Pepperell, therefore, sent a night expedition there, which, however, returned without accomplishing its purpose. But his greatest fear, lest supplies or re-enforcements should get into Louisburg by sea, was set at rest on finding that the field or pack-ice, which had come down out of the St. Lawrence, and the east winds had driven up against the shores of Cape Breton, formed a secure blockade against all comers, himself as well as the enemy. This contingency had not been sufficiently weighed.

Canso fortified.

Meanwhile, Pepperell set to work fortifying Canso. A blockhouse, ready framed, had been sent out for the purpose. This was now set up, garrisoned, and christened Fort Prince William. Some earthworks were also thrown up to cover this new post. In these occupations, or in scouting or exercising, the troops were kept employed until the ice should move off the shores.

French Cruiser driven off.

On the 18th of April a French thirty-gun ship was chased off the coast, while trying to run into Louisburg. Being the better sailer, she easily got clear of the blockading vessels, after keeping up for some hours a sharp, running fight. Even this occurrence does not seem to have fully opened the eyes of the French commandant of Louisburg to the true nature of the danger which threatened him, since he has declared that he thought the vessels he saw watching the harbor were only English privateers. Perhaps nothing about the whole history of this expedition is more strange than that this officer should have remained wholly ignorant of its being at Canso for nearly three weeks.

Effect on the Army.

The army had been lying nearly two weeks inactive, when, to Pepperell’s great surprise as well as joy, Commodore Warren appeared off Canso with four ships of war, and, after briefly communicating with the general, bore away for Louisburg. At last he had received his orders to act in concert with Shirley, and, like a true sailor, he had crowded all sail for the scene of action. His coming put the army in great spirits, for it was supposed to be part of the plan, already concerted, by which the attack should be made irresistible. And for once fortune seems to have determined that the bungling of ministers should not defeat the objects had in view.
