After his defeat in the Assembly, Shirley returned, vexed and disappointed, to his house in Roxbury. A few days later, James Gibson, a Boston merchant, says that he saw him “walking slowly down King 68 Street, with his head bowed down, as if in a deep study.” “He entered my counting-room,” pursues the merchant, “and abruptly said, ‘Gibson, do you feel like giving up the expedition to Louisbourg?’” Gibson replied that he wished the House would reconsider their vote. “You are the very man I want!” exclaimed the governor.[63] They then drew up a petition for reconsideration, which Gibson signed, promising to get also the signatures of merchants, not only of Boston, but of Salem, Marblehead, and other towns along the coast. In this he was completely successful, as all New England merchants looked on Louisbourg as an arch-enemy. The petition was presented, and the question came again before the Assembly. There had been much intercourse between Boston and Louisbourg, which had largely depended on New England for provisions.[64] The captured militiamen of Canseau, who, after some delay, had been sent to Boston, according to the terms of surrender, had used their opportunities to the utmost, and could give Shirley much information concerning the fortress. It was reported that the garrison was mutinous, and that provisions were fallen short, so that the place could not hold out without supplies from France. These, however, could be cut off only by blockading the harbor with a stronger naval force than all the colonies together could supply. 69 The Assembly had before reached the reasonable conclusion that the capture of Louisbourg was beyond the strength of Massachusetts, and that the only course was to ask the help of the mother-country.[65] The reports of mutiny, it was urged, could not be depended on; raw militia in the open field were no match for disciplined troops behind ramparts; the expense would be enormous, and the credit of the province, already sunk low, would collapse under it; we should fail, and instead of sympathy, get nothing but ridicule. Such were the arguments of the opposition, to which there was little to answer, except that if Massachusetts waited for help from England, Louisbourg would be reinforced and the golden opportunity lost. The impetuous and irrepressible Vaughan put forth all his energy; the plan was carried by a single vote. And even this result was said to be due to the accident of a member in opposition falling and breaking a leg as he was hastening to the House.
