Did Sullivan, as one letter states, immediately send word to Stirling to retreat?[150] This would have been the first and natural step. Whoever the commanding officer might be at the Flatbush Pass, it was for him to watch the situation at the outpost line and give orders to the right and left. All depended on what was done at that pass. If the guards there gave way all the others must give way instantly. Whether the word, therefore, reached Stirling or not, we must believe that Sullivan sent it, as he ought to have done, and is reported to have done. As for the general himself and his party, retreat was the only alternative. Leaving the advanced pickets to fall back before the Hessians, they turned towards the British in their rear. Very soon they encountered the light infantry and dragoons, who were now engaging in the attack with the highest dash and spirit. Reinforced by four companies of the guards, the latter captured three pieces of our artillery--the same, doubtless, which had just been playing upon the Hessians, but were now turned, in the retreat, upon the British--and which our gunners defended "heroically" to the last. Sullivan and his men fought well, and apparently in separate parties, until nearly all that had been stationed at the Flatbush Pass succeeded in breaking or making their way through to the lines. [Footnote 150: The supposition that Stirling commanded outside of the lines on Long Island is erroneous. He had command of the reserves in camp (Orders of August 25th), and was the proper officer to call upon to reinforce any part of the outer line in case of attack. Sullivan says, "Lord Stirling commanded the main body without the lines;" by which is meant that he was with the principal force that went out, as he was. Until the attack, the general officer of the day was in charge of the outposts. Sullivan governed himself according to circumstances. He was to be second in command under Putnam within the lines, he writes; but the situation soon required his presence outside, where he was also familiar with the dispositions.]
