Ever since Sir William Howe had been driven from Boston, in the spring of 1776, the opinion prevailed among American generals that, sooner or later, New England would become the battle-ground.[14] This view was sustained by the enemy's seizure of Newport, in December of the same year, so that the Americans were perplexed at finding themselves threatened from this quarter, until the enemy's plans were fully developed. [Sidenote: St. Leger's part.] There was yet another part to the plan concerted between Burgoyne and the British cabinet. It was seen that in proportion as Burgoyne moved down toward Albany, he would have the fertile Mohawk valley on his right. This valley was the great thoroughfare between the Hudson and Lake Ontario, Niagara, and Detroit. In it were many prosperous settlements, inhabited by a vigorous yeomanry, who were the mainstay of the patriot cause in this quarter. The passage to and fro was guarded by Fort Stanwix, which stood where Rome now is, and Fort Oswego, which was situated at the lake. Fort Stanwix was held by the Americans, and Oswego, by the British. Perceiving its value to the Americans not only as a granary, but as a recruiting station, and in view of the danger of leaving it on his flank, Burgoyne decided to march a force through this valley, clear it of enemies, and so effectively bring about a timely cooeperation between the two branches of the expedition. Freed of fear for himself, he could materially aid in the work intrusted to his auxiliary. It followed that the Americans, with whom Burgoyne himself might be contending, would, of necessity, be greatly distressed by their inability to draw either men or supplies from the Mohawk Valley, no less than by the appearance of this force upon their own flank. The command of it was given to Colonel St. Leger, who was ordered to proceed up the St. Lawrence to Oswego, and from thence to Fort Stanwix and Albany. It must be allowed that this plan was well conceived; yet its success depended so much upon all the parts working in harmony together, that to have set it in motion, without consultation or clear understanding between the generals who were to execute it, is inconceivable. At a distance of three thousand miles from the scene of war, the British cabinet undertook to direct complicated military operations, in which widely separated armies were to take part. General Burgoyne received his orders on the spot. General Howe did not receive his until the 16th of August; his army was then entering Chesapeake Bay. Burgoyne was being defeated at Bennington, at the time Howe was reading his despatch, and learning from it what he had not known before; namely, that he was expected to cooeperate with the army of Burgoyne. These facts will so sufficiently illustrate the course that events were taking, as to foreshadow their conclusion to the feeblest understanding.
