On the 31st of July, just as Burgoyne reached Fort Edward, where he stuck fast for six weeks, Howe’s armament was off the Capes of the Delaware. The prevailing summer wind on the American coast is south-south-west, fair for ascending the river; but information was received that the enemy had obstructed the channel, which lends itself to such defences for some distance below Philadelphia. Therefore, although after occupying the city the free navigation of the river to the sea would be essential to maintaining the position,—for trial had shown that the whole army could not assure communications by land with New York, the other sea base,—Howe decided to prosecute his enterprise by way of the Chesapeake, the ascent of which, under all the conditions, could not be seriously impeded. A fortnight more was consumed in contending against the south-west winds and calms, before the fleet anchored on the 15th of August within the Capes of the Chesapeake; and yet another week passed before the head of the Bay was reached. On the 25th the troops landed. Washington, though so long in doubt, was on hand to dispute the road, but in inferior force; and Howe had no great difficulty in fighting his way to Philadelphia, which was occupied on the 26th of September. A week earlier Burgoyne had reached Stillwater, on the west bank of the Hudson, the utmost point of his progress, where he was still twenty miles from Albany. Three weeks later, confronted by overwhelming numbers, he was forced to capitulate at Saratoga, whither he had retreated.
