When the news of the French alliance arrived, in the spring of 1778, there was a general feeling of elation. People were over-confident. It seemed as if the British might be driven from the country in the course of that year. Some changes occurred in both the opposing armies. A great deal of fault was found in England with Howe and Burgoyne. The latter was allowed to go home in the spring, and took his seat in Parliament while still a prisoner on parole. He was henceforth friendly to the Americans, and opposed the further prosecution of the war. Sir William Howe resigned his command in May and went home in order to defend his conduct. Shortly before his appointment to the chief command in America, he had uttered a prophecy somewhat notable as coming from one who was about to occupy such a position. In a speech at Nottingham he had expressed the opinion that the Americans could not be subdued by any army that Great Britain could raise! [Sidenote: Howe is superseded by Clinton.] Howe was succeeded in the chief command by Sir Henry Clinton. His brother, Lord Howe, remained in command of the fleet until the autumn, when he was succeeded by Admiral Byron. During the winter the American army had received a very important reinforcement in the person of Baron von Steuben, an able and highly educated officer who had served on the staff of Frederick the Great. Steuben was appointed inspector-general and taught the soldiers Prussian discipline and tactics until the efficiency of the army was more than doubled. About the time of Sir William Howe's departure, Charles Lee was exchanged, and came back to his old place as senior major-general in the Continental army. Since his capture there had been a considerable falling off in his reputation, but nothing was known of his treasonable proceedings with the Howes. Probably no one in the British army knew anything about that affair except the Howes and their private secretary Sir Henry Strachey. Lee saw that the American cause was now in the ascendant, and he was as anxious as ever to supplant Washington.
