On the other hand, should he now cross the Hudson, with intent to bring on a decisive battle,--and his crossing meant just this,--Burgoyne knew that he must drop his communications with Canada, because he could not afford the guards necessary to keep them open. Already he had been weakened by the loss of more than fifteen hundred men, without counting the Indians who had so basely deserted him; St. Leger had failed him in his utmost need. On his left, the Americans were watching their chance to strike a blow in his rear. Burgoyne therefore felt that, from the moment he should put the Hudson between his army and its only way of retreat, all must be staked on the doubtful issue of battle. He decided to make the gambler's last throw. Burgoyne himself has said that his orders left him no choice but to go on. It is evident he construed them to his own wishes. He still believed his six thousand excellent soldiers, with their superb artillery, would prove themselves more than a match for twice their own number of undisciplined yeomanry. He would not admit even the possibility of defeat. He felt confident of beating Gates with ease. In choosing to fight, rather than retreat, Burgoyne, perhaps, acted from the impulse of a brave nature, rather than the promptings of his sober judgment, as he was bound to do; since he had known for some time that Sir William Howe had gone to Pennsylvania, without making any definite preparations to come to his assistance. Notwithstanding this assurance, that a most important part of the plan of campaign had failed, through no fault of his, Burgoyne seems to have put his trust in the chapter of accidents, rather than remain inactive until it was certain he would be supported from New York. Not one solitary circumstance, except faith in the valor of his troops, favored a further advance at this time. But his gallant little army was ready to follow him, the enemy was within striking distance, and so Burgoyne marched on, bemoaning his ill luck, but with the pluck characteristic of the man. On the thirteenth the British army crossed the Hudson, by a bridge of boats, to Saratoga. Burgoyne took with him provisions for five weeks, which were loaded in bateaux and floated down the river as he advanced. As yet he knew comparatively nothing of what preparations the Americans were making to receive him, and but little about the country he was in. But he did know that the patriot army had at last faced about, and that was enough to rouse the spirit of his soldiers to the highest pitch. [Illustration: BURGOYNE'S ORDER OF BATTLE. 19th September.
