John de Dieu, with attendant nunnery and hospitals. The streets crossed at right angles, and five gates in the walls on the harbor side communicated with the wharves. Such was the greatest stronghold in North America in 1745, the famous Louisbourg fortress. The people of New England, whose commerce was being preyed upon by privateers which found refuge in its harbor, and whose frontiers were harassed by forays thence directed, we are told by the historian, "looked with awe upon the sombre walls of Louisbourg, whose towers rose like giants above the northern seas." But the Puritans were not wont to lie still under such inflictions, nor to confine their efforts to prayers alone. Massachusetts planned an attack, and the command of the expedition was given William Pepperell of Kittery, a merchant ignorant of the art of war. Then followed one of the most extraordinary events in history. A fleet of about a hundred vessels carried a force of forty-one hundred undisciplined militia upon a Puritan crusade, which was started with religious services, the eloquent preacher, George Whitefield, imploring a blessing and giving them the motto, _Nil desperandum, Christo duce_. They rendezvoused at Canso, meeting there Commodore Warren and the British West Indian fleet by arrangement, and landing at Gabarus Bay, west of Louisbourg, April 30, 1745. They did not know much about war, but they set fire to some storehouses, and the black smoke drove down in such volumes upon the Royal Battery at the bottom of the harbor that its scared French defenders spiked the guns and fled in the night. The Puritans took possession, beat off the French who attacked them, got smiths at work, who drilled out the spikes, and soon from this, the key to the position, they turned the guns upon the town. Then began a regular siege, though most unscientific in manner. They captured a French ship with stores and reinforcements, and by June had breached the walls twenty-four feet at the King's Bastion, dismounted all the neighboring guns, made the Goat Island Battery untenable, and ruined the town by showers of bombs and red-hot balls. Upon June 15th the British fleet of ten ships was drawn up off the harbor entrance for an attack, and the land forces were arrayed to assault the West Gate, when the French commander, knowing he could hold out no longer, decided to surrender, and on June 17th, the forty-ninth day of the siege, he capitulated.
