The crisis at length arrived. There was at Concord, near Boston, a large magazine of military stores. General Gage sent a force to destroy it. The patriots collected in considerable numbers to oppose the British troops, and drove them back, with a heavy loss, into the city. This engagement, though little more than a skirmish, was called the Battle of Lexington. If its results were to be taken into consideration, few battles have been of more importance. Brethren had shed each other's blood. Both parties were exasperated beyond control. The patriots felt their power; the royalists burned to wipe out the disgrace their arms had received. General Gage now regularly fortified Boston, which was in its turn besieged by the rebels. The whole continent was up in arms. Another successful enterprise had been undertaken by a leader of irregulars, who had seized the Ports of Ticonderoga and Crown Point, which gave the patriots the command of Lake George and the head of Lake Champlain, always recognised as the keys of Canada. The patriots had by this time formed a regular Government. Each of the colonies had sent delegates to a general assembly held at Philadelphia, to which the name of the Congress was given. The Congress had authorised the formation of an army and had appointed as Commander-in-chief a gentleman of Virginia of good repute, Colonel George Washington. He was well known as a bold leader in frontier warfare against the Indians, and had also seen service against the French; besides this, he was a man of the highest moral qualities, which had gained him the respect of his fellow-colonists. The event which had induced the Government to despatch my ship and others so hurriedly to the North American station was the battle of Bunker's Hill, the news of which had just been received. The engagement itself would not have been of much consequence had it not proved that the rebels were resolved to fight it out to the last. The Americans, besieging Boston, had fortified a height above the city called Bunker's Hill. General Gage resolved to dislodge them and to endeavour to raise the siege. Our troops, after much hard fighting and considerable loss, claimed the victory, having driven the enemy from the heights; but the Americans quickly rallied, and, many reinforcements coming up, the city was more closely invested than ever.
