While there was so little in the events of the Southern campaign to bring comfort to the rebels, in the North their cause suffered a moral blow which was felt at the moment to be almost as grave as any military disaster. Here the principal American force was commanded by one of the ablest soldiers the Rebellion had produced, a man who might well have disputed the pre-eminent fame of Washington if he had not chosen rather to challenge--and with no contemptible measures of success--that of Iscariot. Benedict Arnold was, like Washington, a professional soldier whose talent had been recognized before the war. He had early embraced the revolutionary cause, and had borne a brilliant part in the campaign which ended in the surrender of Burgoyne. There seemed before him every prospect of a glorious career. The motives which led him to the most inexpiable of human crimes were perhaps mixed, though all of them were poisonous. He was in savage need of money to support the extravagance of his private tastes: the Confederacy had none to give, while the Crown had plenty. But it seems also that his ravenous vanity had been wounded, first by the fact that the glory of Burgoyne's defeat had gone to Gates and not to him, and afterwards by a censure, temperate and tactful enough and accompanied by a liberal eulogy of his general conduct, which Washington had felt obliged to pass on certain of his later military proceedings. At any rate, the "ingratitude" of his country was the reason he publicly alleged for his treason; and those interested in the psychology of infamy may give it such weight as it may seem to deserve. For history the important fact is that Arnold at this point in the campaign secretly offered his services to the English, and the offer was accepted.
