Treachery, now linked to military disaster, made Washington's position terrible. Charles Lee, Horatio Gates, and Richard Montgomery were three important officers of the regular British army who fought on the American side. Montgomery had been killed at Quebec; the defects of Gates were not yet conspicuous; and Lee was next to Washington the most trusted American general. The names Washington and Lee of the twin forts on opposite sides of the Hudson show how the two generals stood in the public mind. While disaster was overtaking Washington, Lee had seven thousand men at North Castle on the east bank of the Hudson, a few miles above Fort Washington, blocking Howe's advance farther up the river. On the day after the fall of Fort Washington, Lee received positive orders to cross the Hudson at once. Three days later Fort Lee fell, and Washington repeated the order. Lee did not budge. He was safe where he was and could cross the river and get away into New Jersey when he liked. He seems deliberately to have left Washington to face complete disaster and thus prove his incompetence; then, as the undefeated general, he could take the chief command. There is no evidence that he had intrigued with Howe, but he thought that he could be the peacemaker between Great Britain and America, with untold possibilities of ambition in that rôle. He wrote of Washington at this time, to his friend Gates, as weak and "most damnably deficient." Nemesis, however, overtook him. In the end he had to retreat across the Hudson to northern New Jersey. Here many of the people were Tories. Lee fell into a trap, was captured in bed at a tavern by a hard-riding party of British cavalry, and carried off a prisoner, obliged to bestride a horse in night gown and slippers. Not always does fate appear so just in her strokes. In December, though the position of Washington was very bad, all was not lost. The chief aim of Howe was to secure the line of the Hudson and this he had not achieved. At Stony Point, which lies up the Hudson about fifty miles from New York, the river narrows and passes through what is almost a mountain gorge, easily defended. Here Washington had erected fortifications which made it at least difficult for a British force to pass up the river. Moreover in the highlands of northern New Jersey, with headquarters at Morristown, General Sullivan, recently exchanged, and General Gates now had Lee's army and also the remnants of the force driven from Canada. But in retreating across New Jersey Washington had been forsaken by thousands of men, beguiled in part by the Tory population, discouraged by defeat, and in many cases with the right to go home, since their term of service had expired. All that remained of Washington's army after the forces of Sullivan and Gates joined him across the Delaware in Pennsylvania, was about four thousand men.
