The sight of the American flag hauled down, and the British flag waving in its place, told Washington of the surrender. His instant care was for the safety of the upper country, now that the lower defences of the Hudson were at an end. Before he knew any thing about the terms of capitulation, he wrote to General Lee, informing him of the surrender, and calling his attention to the passes of the Highlands and those which lay east of the river; begging him to have such measures adopted for their defence as his judgment should suggest to be necessary. “I do not mean,” added he, “to advise abandoning your present post, contrary to your own opinion; but only to mention my own ideas of the importance of those passes, and that you cannot give too much attention to their security, by having works erected on the most advantageous places for that purpose.” Lee, in reply, objected to removing from his actual encampment at Northcastle. “It would give us,” said he, “the air of being frightened; it would expose a fine, fertile country to their ravages; and I must add, that we are as secure as we could be in any position whatever.” After stating that he should deposit his stores, &c., in a place fully as safe, and more central than Peekskill, he adds: “As to ourselves, light as we are, several retreats present themselves. In short, if we keep a good look-out, we are in no danger; but I must entreat your Excellency to enjoin the officers posted at Fort Lee, to give us the quickest intelligence, if they observe any embarkation on the North River.” As to the affair of Fort Washington, all that Lee observed on the subject was: “Oh, general, why would you be over-persuaded by men of inferior judgment to your own? It was a cursed affair.” Lee’s allusion to men of inferior judgment, was principally aimed at Greene, whose influence with the commander-in-chief seems to have excited the jealousy of other officers of rank. So Colonel Tilghman, Washington’s aide-de-camp, writes on the 17th, to Robert R. Livingston of New York, “We were in a fair way of finishing the campaign with credit to ourselves, and, I think, to the disgrace of Mr. Howe; and, had the general followed his own opinion, the garrison would have been withdrawn immediately upon the enemy’s falling down from Dobbs’ Ferry. But General Greene was positive that our forces might at any time be drawn off under the guns of Fort Lee. Fatal experience has evinced the contrary.”[134]
