And now England at last did what, if she were determined to enforce her will upon the colonists, she ought to have done at least five years before. She sent out an army on a scale at least reasonably adequate to the business for which it was designed. It consisted partly of excellent British troops and partly of those mercenaries whom the smaller German princes let out for hire to those who chose to employ them. It was commanded by Lord Howe. The objective of the new invasion – for the procrastination of the British Government had allowed the war to assume that character – was the city of New York.
New York harbour possesses, as anyone who enters it can see, excellent natural defences. Manhattan Island, upon which the city is built, lies at the mouth of the Hudson between two arms of that river. At the estuary are a number of small islets well suited for the emplacement of powerful guns. The southern bank runs northward into a sharp promontory, at the end of which now stands the most formidable of American fortresses. The northern approach is covered by Long Island. The British command decided on the reduction of Long Island as a preliminary to an assault upon the city. The island is long and narrow, and a ridge of high ground runs down it like a backbone. This ridge Washington's army sought to hold against the attack of the British forces. It was the first real battle of the war, and it resulted in a defeat so overwhelming that it might well have decided the fate of America had not Washington, as soon as he saw how the day was going, bent all his energies to the tough task of saving his army. It narrowly escaped complete destruction, but ultimately a great part succeeded, though with great loss and not a little demoralization, in reaching Brooklyn in safety.
The Americans still held New York, the right bank of the Hudson; but their flank was dangerously threatened, and Washington, true to his policy, preferred the damaging loss of New York to the risk of his army. He retired inland, again offered battle, was again defeated and forced back into Pennsylvania. So decided did the superiority of the British army prove to be that eventually Philadelphia itself, then the capital of the Confederacy, had to be abandoned.
Meanwhile another British army under the command of General Burgoyne held Canada. That province had shown no disposition to join in the revolt; an early attempt on the part of the rebels to invade it had been successfully repelled. Besides English and German troops, Burgoyne had the aid of several tribes of Indian auxiliaries, whose aid the British Government had been at some pains to secure – a policy denounced by Chatham in a powerful and much-quoted speech. Burgoyne was a clever and imaginative though not a successful soldier. He conceived and suggested to his Government a plan of campaign which was sound in strategic principle, which might well have succeeded, and which, if it had succeeded, would have dealt a heavy and perhaps a decisive blow to American hopes. How far its failure is to be attributed to his own faulty execution, how far to the blunders of the Home Government, and how far to accidents which the best general cannot always avoid, is still disputed. But that failure was certainly the turning-point of the war.
Burgoyne's project was this: He proposed to advance from Canada and push across the belt of high land which forms the northern portion of what is now New York State, until he struck the upper Hudson. Howe was at the same time to advance northward up the Hudson, join hands with him and cut the rebellion in two.
It was a good plan. The cutting off and crushing of one isolated district after another is just the fashion in which widespread insurrectionary movements have most generally been suppressed by military force. The Government accepted it, but, owing as it would seem to the laziness or levity of the English Minister involved, instructions never reached Howe until it was too late for him to give effective support to his colleague. All, however, might have prospered had Burgoyne been able to move more rapidly. His first stroke promised well. The important fort of Ticonderoga was surprised and easily captured, and the road was open for his soldiers into the highlands. But that advance proved disastrously slow. Weeks passed before he approached the Hudson. His supplies were running short, and when he reached Saratoga, instead of joining hands with Howe he found himself confronted by strongly posted American forces, greatly outnumbering his own ill-sustained and exhausted army. Seeing no sign of the relief which he had expected to the south – though as a fact Howe had by this time learnt of the expedition and was hastening to his assistance – on October 6, 1777, he and his army surrendered to the American commander, General Gates.
The effect of Burgoyne's surrender was great in America; to those whose hopes had been dashed by the disaster of Long Island, the surrender of New York and Washington's enforced retreat it brought not only a revival of hope but a definite confidence in ultimate success. But that effect was even greater in Europe. Its immediate fruit was Lord North's famous "olive branch" of 1778; the decision of the British Government to accept defeat on the original issue of the war, and to agree to a surrender of the claim to tax the colonists on condition of their return to their allegiance. Such a proposition made three years earlier would certainly have produced immediate peace. Perhaps it might have produced peace even as it was – though it is unlikely, for the declaration had filled men's souls with a new hunger for pure democracy – if the Americans had occupied the same isolated position which was theirs when the war began. But it was not in London alone that Saratoga had produced its effect. While it decided the wavering councils of the British Ministry in favour of concessions, it also decided the wavering councils of the French Crown in favour of intervention.
As early as 1776 a mission had been sent to Versailles to solicit on behalf of the colonists the aid of France. Its principal member was Benjamin Franklin, the one revolutionary leader of the first rank who came from the Northern colonies. He had all the shrewdness and humour of the Yankee with an enlarged intelligence and a wide knowledge of men which made him an almost ideal negotiator in such a cause. Yet for some time his mission hung fire. France had not forgotten her expulsion from the North American continent twenty years before. She could not but desire the success of the colonists and the weakening or dismemberment of the British Empire. Moreover, French public opinion – and its power under the Monarchy, though insufficient, was far greater than is now generally understood – full of the new ideals which were to produce the Revolution, was warmly in sympathy with the rebellion. But, on the other hand, an open breach with England involved serious risks. France was only just recovering from the effects of a great war in which she had on the whole been worsted, and very decidedly worsted, in the colonial field. The revolt of the English colonies might seem a tempting opportunity for revenge; but suppose that the colonial resistance collapsed before effective aid could arrive? Suppose the colonists merely used the threat of French intervention to extort terms from England and then made common cause against the foreigner? These obvious considerations made the French statesmen hesitate. Aid was indeed given to the colonial rebels, especially in the very valuable form of arms and munitions, but it was given secretly and unofficially, with the satirist Beaumarchais, clever, daring, unscrupulous and ready to push his damaged fortunes in any fashion, as unaccredited go-between. But in the matter of open alliance with the rebels against the British Government France temporized, nor could the utmost efforts of Franklin and his colleagues extort a decision.
Saratoga extorted it. On the one hand it removed a principal cause of hesitation. After such a success it was unlikely that the colonists would tamely surrender. On the other it made it necessary
