Louisbourg was unique in all America, and that was its undoing. It was the one sentinel beside the gateway to New France; therefore it ought to be taken before Quebec and Canada were attacked. It was the one corsair lying in perpetual wait beside the British lines of seaborne trade; therefore it must be taken before British shipping could be safe. It was the one French sea link between the Old World and the New; therefore its breaking was of supreme importance. It was the one real fortress ever heard of in America, and it was in absolutely alien hands; therefore, so ran New England logic, it was most offensive to all true Britons, New Englanders, and Puritans; to all rivals in smuggling, trade, and privateering; and to all right-thinking people generally.
The weakness of Louisbourg was very welcome news to energetic Massachusetts. In 1744, when Frederick the Great had begun the War of the Austrian Succession and France had taken arms against Great Britain, du Quesnel, the governor of Louisbourg, who had received the intelligence of these events some weeks before the alert Bostonians, at once decided to win credit by striking the first blow. He was much disliked in Louisbourg. He drank hard, cursed his subordinates when in his cups, and set the whole place by the ears. Moreover, many of those under him wished to avoid giving the British Americans any provocation, in the hope that the war might be confined to Europe. But none dared to refuse a legal and positive order. So in May his expedition left for Canso, where there was a little home-made British fort on the strait between Cape Breton and the mainland of Nova Scotia. The eighty fishermen in Canso surrendered to du Vivier, the French commander, who sent them on to Boston, after burning their fort to the ground. Elated by this somewhat absurd success, and strengthened by nearly a hundred regulars and four hundred Indians, who raised his total force to at least a thousand men, du Vivier next proceeded against Annapolis on the west side of Nova Scotia. But Mascarene, the British commander there, stood fast on his defence, though his men were few and his means small. The Acadian French in the vicinity were afraid to join du Vivier openly. The siege dragged on. The British received a slight reinforcement. The French did not. And in September du Vivier suddenly retired without attempting an assault.
The burning of Canso and the attack on Annapolis stirred up the wrath of New England. A wild enthusiast, William Vaughan, urged Governor Shirley of Massachusetts to make an immediate counter-attack. Shirley was an English lawyer, good at his own work, but very anxious to become famous as a conqueror. He lent a willing ear to Vaughan, and astounded the General Court of Massachusetts on January 21, 1745, by first inducing the members to swear secrecy and then asking them to consider a plan for a colonial expedition against Louisbourg. He and they were on very good terms. But they were provincial, cautious, and naturally slow when it came to planning campaigns and pledging their credit for what was then an enormous sum of money. Nor could they be blamed. None of them knew much about armies and navies; most thought Louisbourg was a real transatlantic Dunkirk; and all knew that they were quite insolvent already. Their joint committee of the two Houses reported against the scheme; whereupon each House carried a secret adverse vote by a large majority.
But, just before these votes were taken, a Puritan member from a country district wrestled in what he thought confidential prayer with such loud ejaculations that an eavesdropper overheard him and passed the secret on. Of course the momentous news at once began to run like wildfire through the province. Still, the 'Noes had it,' both in the country and the House. Shirley was dejected and in doubt what to do next. But James Gibson, the merchant militiaman, suddenly hit on the idea of getting up a petition among the business community. The result surpassed every expectation. All the merchants were eager for attack. Louisbourg embodied everything they feared and hated: interference with seaborne commerce, rank popery, French domination, trouble with Acadia, and the chance of being themselves attacked. When the petition was presented to both Houses, the whole subject was again debated. Provincial insolvency and the absence of either a fleet or an army were urged by the Opposition. But the fighting party put forth all their strength and pleaded that delay meant reinforcements for Louisbourg and a good chance lost for ever. The vote would have been a tie if a member of the Opposition had not slipped and broken his leg as he was hurrying down to the House. Once the decision had been reached, however, all did their best to ensure success.
Shirley wrote to his brother governors. Vaughan galloped off post-haste to New Hampshire with the first official letter. Gibson led the merchants in local military zeal. The result was that Massachusetts, which then included Maine, raised over 3,000 men, while New Hampshire and Connecticut raised about 500 each. Rhode Island concurred, but ungraciously and ineffectually late. She nursed two grudges against Massachusetts, one about the undeniably harsh treatment meted out to her great founder, Roger Williams, the other about that most fruitful source of inter-provincial mischief-making, a disputed boundary. New York lent some guns, which proved very useful. The remaining colonies did nothing.
Shirley's choice of a commander-in-chief wisely fell on William Pepperrell. There was no military leader in the whole of New England. So the next most suitable man was the civilian who best combined the necessary qualities of good sense, sound knowledge of men and affairs, firmness, diplomacy, and popularity. Popularity was essential, because all the men were volunteers. Pepperrell, who answered every reasonable test, went through the campaign with flying colours and came out of it as the first and only baronet of Massachusetts. He was commissioned as major-general by all three contributing provinces, since none of them recognized any common authority except that of the crown. He was ably seconded by many leading men who, if not trained soldiers, were at least accustomed to the organization of public life; for in those days the word politician had not become a term of reproach in America, and the people were often represented by men of the highest character.
The financial difficulty was overcome by issuing letters of credit, which were afterwards redeemed by the Imperial government, at a total cost of nearly a quarter of a million sterling. There was no time and there were no means to change the militia into an army. But many compensating advantages helped to make up for its deficiencies. The men volunteered eagerly. They were all very keen to fight the French. Most of them understood the individual use of firearms. Many of them had been to sea and had learned to work together as a crew. Nearly all of them had the handiness then required for life in a new country. And, what with conviction and what with prejudice, they were also quite disposed to look upon the expedition as a sort of Crusade against idolatrous papists, and therefore as a very proper climax to the Great Awakening which had recently roused New England to the heights of religious zealotry under the leadership of the famous George Whitefield himself.
Strangely enough, neither Whitefield nor his friend Pepperrell was at all sure that the expedition was a wise or even a godly venture. Whitefield warned Pepperrell that he would be envied if he succeeded and abused if he failed. The Reverend Thomas Prince openly regretted the change of enemy. 'The Heavenly shower is over. From fighting the Devil they needs must turn to fighting the French.' But Parson Moody, most truculent of Puritans, had no doubts whatever. The French, the pope, and the Devil were all one to him; and when he embarked as senior chaplain he took a hatchet with which to break down the graven images of Louisbourg. In the end Whitefield warmed up enough to give the expedition its official motto: 'Nil desperandum Christo Duce.' The 'Never Despair' heartened the worldlings. The 'Christ our Commander' appealed to the 'Great Awakened.' And the whole saying committed him to nothing particular concerning the issue at stake.
The three militia contingents numbered 4,270 men. The three naval contingents had 13 vessels mounting 216 guns. In addition to both these forces there were the transports, which had considerable crews. But all these together, if caught on the open sea, would be no match for a few regular men-of-war. New England had no navy, though the New Englanders had enjoyed a good deal of experience in minor privateering against the Spaniards during the last few years, as well as a certain amount of downright piracy in time of peace, whenever a Frenchman or a Spaniard could be safely taken at a disadvantage. So Shirley asked Commodore Warren, commanding the North American station, to lend his aid. Warren had married an American and was very well disposed towards the colonists. But, having no orders from England, he at first felt obliged to refuse. Within a short time, however, he was given a free hand by the Imperial government, which authorized him to concert measures with Shirley 'for the annoyance of the enemy, and for his Majesty's Service in North America.'
Warren immediately sailed for Canso with three men-of-war and sent for another to join him. His wait for orders made him nearly three weeks later than the New Englanders in arriving at the rendezvous. But this delay, due to no fault of his own, was really an advantage to the New England militia, who thus had a chance of learning a little more drill and discipline. His four vessels carried 180 guns and 1,150 men at full strength. The thirteen Provincial armed vessels carried more than 1,000 men. No exact returns were ever made out for the transports. But as '68 lay at anchor' in Canso harbour, while others 'came dropping in from day to day,' as there were 4,270 militiamen on board, in addition to all the stores, and as the French counted '96 transports' making for Gabarus Bay, there could not have been less than 100, while the crews could hardly have mustered less than an average of 20 men each. The grand total, at the beginning of the expedition, could not, therefore, have been less than 8,000 men, of all sorts put together—over 4,000 American Provincial militia, over 1,000 men of the Royal Navy, quite 1,000 men aboard the Provincial fighting vessels, and at least 2,000 more as crews to work the transports.
