This movement was made with the view of inducing General Washington to quit his fortified camp, and approach the Delaware,[59] in which event, the British general expected to bring on an engagement on ground less disadvantageous than that now occupied by the American army. But that officer understood the importance of his position too well to abandon it. On the first intelligence that the enemy was in motion, he drew out his whole army, and formed it, to great advantage, on the heights in front of his camp. This position was constantly maintained. The troops remained in order of battle during the day; and, in the night, slept on the ground to be defended. In the mean time the Jersey militia, with an alacrity theretofore unexampled in that state, took the field in great numbers. They principally joined General Sullivan, who had retired from Princeton, behind the Sourland hills towards Flemingtown, where an army of some respectability was forming, which could readily co-operate with that under the immediate inspection of the Commander-in-chief. [Footnote 59: General Howe's letter.] The settled purpose of General Washington was to defend his camp, but not to hazard a general action on other ground. He had therefore determined not to advance from the heights he occupied, into the open country, either towards the enemy, or the Delaware. The object of General Howe seems to have been, by acting on his anxiety for Philadelphia, to seduce him from the strong ground about Middlebrook, and tempt him to approach the Delaware, in the hope of defending its passage. Should he succeed in this, he had little doubt of being able to bring on an engagement, in which he counted with certainty on victory. The considerations which restrained General Howe from attempting to march through Jersey, leaving the American army in full force in his rear, had determined Washington to allow him to proceed to the Delaware, if such should be his intention. In that event, he had determined to throw those impediments only in the way of the hostile army which might harass and retard its march; and, maintaining the high and secure grounds north of the road to be taken by the enemy, to watch for an opportunity of striking some important blow with manifest advantage.
