Benedict Arnold, who had been wounded at Quebec, was now at Crown Point. Competent critics of the war have held that what Arnold now did saved the Revolution. In another scene, before the summer ended, the British had taken New York and made themselves masters of the lower Hudson. Had they reached in the same season the upper Hudson by way of Lake Champlain they would have struck blows doubly staggering. This Arnold saw, and his object was to delay, if he could not defeat, the British advance. There was no road through the dense forest by the shores of Lake Champlain and Lake George to the upper Hudson. The British must go down the lake in boats. This General Carleton had foreseen and he had urged that with the fleet sent to Quebec should be sent from England, in sections, boats which could be quickly carried past the rapids of the Richelieu River and launched on Lake Champlain. They had not come and the only thing for Carleton to do was to build a flotilla which could carry an army up the lake and attack Crown Point. The thing was done but skilled workmen were few and not until the 5th of October were the little ships afloat on Lake Champlain. Arnold, too, spent the summer in building boats to meet the attack and it was a strange turn in warfare which now made him commander in a naval fight. There was a brisk struggle on Lake Champlain. Carleton had a score or so of vessels; Arnold not so many. But he delayed Carleton. When he was beaten on the water he burned the ships not captured and took to the land. When he could no longer hold Crown Point he burned that place and retreated to Ticonderoga. By this time it was late autumn. The British were far from their base and the Americans were retreating into a friendly country. There is little doubt that Carleton could have taken Fort Ticonderoga. It fell quite easily less than a year later. Some of his officers urged him to press on and do it. But the leaves had already fallen, the bleak winter was near, and Carleton pictured to himself an army buried deeply in an enemy country and separated from its base by many scores of miles of lake and forest. He withdrew to Canada and left Lake Champlain to the Americans. CHAPTER III. INDEPENDENCE
