On the following day, the 29th, Howe waited for reinforcements. On the 30th, the rain postponed an intended attack. On the 31st the weather proved fine about noon, but the British General "did not think proper to put his former intentions in execution." The next morning, November 1st, there was a further excuse for not attacking: Washington during the night had fallen back to the almost unassailable heights of North Castle, in his rear. Howe was thus again baffled in his attempt to bring the Americans to a decisive engagement, or to surround them, and he now turned his attention to another line of campaign. Stedman, the British historian, probably gives the correct reason why Washington was not followed. The American position, he says, was now "so advantageous that any attack on them must have proved unsuccessful, for the river Croton stretched along their front, and their rear was defended by woods and heights. Convinced that it was part of the enemy's system studiously to avoid an action, and that their knowledge of the country enabled them to execute this system with advantage, General Howe resolved to cease an ineffectual pursuit, and employ himself in the reduction of King's Bridge and Fort Washington." This accomplished, he could then push on to Philadelphia and close the year's operations with the occupation of that place. The capture of two cities, the successive defeats inflicted upon the Americans, and the good prospect of ending the rebellion in the next campaign, would be a brilliant military record with which to gratify the home government. FORT WASHINGTON. Howe broke up his camp near White Plains on November 5th, and marched west to the Hudson at Dobb's Ferry. Knyphausen, who had lately arrived with a second division of "foreigners," had already been despatched to King's Bridge. After various movements and delays, the entire British force also moved on the 12th to the immediate vicinity of the bridge, and dispositions were made to attack and capture Fort Washington. On the 15th, Howe sent a summons for the surrender of the fort, in which he intimated that a refusal to comply would justify the putting of the garrison to the sword.
