It thus appears that in the plan of a triple invasion upon converging lines the ministry were dealing with too many unknown quantities. They were running a prodigious risk for the sake of an advantage which in itself was extremely open to question; for should it turn out that the strength of the Tory party was not sufficiently great to make the junction of the three armies at Albany at once equivalent to the complete conquest of the state, then the end for which the campaign was undertaken could not be secured without supplementary campaigns. Neither a successful march up and down the Hudson river nor the erection of a chain of British fortresses on that river could effectually cut off the southern communications of New England, unless all military resistance were finally crushed in the state of New York. The surest course for the British, therefore, would have been to concentrate all their available force at the mouth of the Hudson, and continue to make the destruction of Washington's army the chief object of their exertions. In view of the subtle genius which he had shown during the last campaign, that would have been an arduous task; but, as events showed, they had to deal with his genius all the same on the plan which they adopted, and at a great disadvantage. [Sidenote: Danger from New England ignored] Another point which the ministry overlooked was the effect of Burgoyne's advance upon the people of New England. They could reasonably count upon alarming the yeomanry of New Hampshire and Massachusetts by a bold stroke upon the Hudson, but they failed to see that this alarm would naturally bring about a rising that would be very dangerous to the British cause. Difficult as it was at that time to keep the Continental army properly recruited, it was not at all difficult to arouse the yeomanry in the presence of an immediate danger. In the western parts of New England there were scarcely any Tories to complicate the matter; and the flank movement by the New England militia became one of the most formidable features in the case.
