He had many difficulties to contend with. Military matters did not run smoothly. In September, 1763, there had been a dangerous mutiny among the troops at Quebec. It was caused by an ill-timed order sent out from home to the effect that the soldiers should pay for their rations; and serious consequences might have followed but for the prompt and firm attitude of the general and his officers. At Quebec, Murray combined civil and military powers; but after civil administration had been proclaimed, though his government included the whole of the province as constituted by the Royal proclamation, he was left without authority over the troops at Montreal, where Burton jealously retained an independent military command. The inevitable result was to fetter his action to a great extent, to give to the Canadians the impression of divided authority,[38] and to accentuate friction between soldiers and civilians, which culminated in an assault at Montreal in December, 1764, on a magistrate named Walker, who had made himself specially obnoxious to the officers of the garrison. Two years later the supposed perpetrators of the outrage were tried and acquitted, but the affair left ill feeling behind it, and Walker remained an active and pertinacious opponent of the British Government in Canada. [Sidenote: The Protestant minority.] Among the Canadian population there were various causes of unrest. The priesthood were anxious as to their position and privileges. The depreciation of the paper money, which had been issued under the French régime, gave trouble. The law was in a state of chaos; and, most of all, the first Governor of Canada had to withstand the pretensions of the handful of Protestants, in 1764 about 200 in number, in 1766 about 450, who wished to dominate the French Canadians, alien in religion and in race. [Sidenote: Murray leaves for England and is succeeded by Carleton.] Against the claims of this small but noisy and intriguing minority Murray resolutely set his face, but the difficulties which arose led to his being summoned home. He left Canada for England towards the end of June, 1766, and though he retained the post of Governor till April, 1768, he never returned to Quebec.
