Burgoyne's March to Saratoga, 1777 .-- While Howe was marching to Philadelphia, General Burgoyne was marching southward from Canada.
It had been intended that Burgoyne and Howe should seize the line of the Hudson and cut New England off from the other states.

But the orders reached Howe too late, and he went southward to Philadelphia.

Burgoyne, on his part, was fairly successful at first, for the Americans abandoned post after post.

But when he reached the southern end of Lake Champlain, and started on his march to the Hudson, his troubles began.

The way ran through a wilderness.
