Enough has been said to show that only heroic measures could now save the American cause. Fortunately Washington was surrounded by a little knot of officers of approved fidelity, whose spirit no reverses could subdue. And though a calm retrospect of so many disasters, with all the jealousies, the defections, and the terror which had followed in their wake, might well have carried discouragement to the stoutest hearts, this little band of heroes now closed up around their careworn chief, and like the ever-famous Guard at Waterloo, were fully resolved to die rather than surrender. This was much. It was still more when Washington found his officers inspired by the same hope of striking the enemy unawares which he himself had all along secretly entertained. The hope was still further encouraged by a reenforcement of Pennsylvania militia, whose pride had been aroused at seeing the invader's vedettes in sight of their capital. These were posted at Bristol, under Cadwalader,[1] as a check to Count Donop, while what was left of the old army was guarding the crossings above, as a check to Rall. To do something, and to do it quickly, were equally imperative, because the term of the regular troops would expire in a few days more, and no one realized better than the commander-in-chief that the militia could not long be held together inactive in camp. [Sidenote: Rall's danger.] The isolated situation of Rall and Donop seemed to invite attack. Their fancied security seemed also to presage success. An inexorable necessity called loudly for action before conditions so favorable should be changed by the freezing up of the Delaware when, if the enemy had any enterprise whatever, the river would no longer prevent, but assist, his marching into Philadelphia, and perhaps dictating a peace from the halls of Congress. Donop being considerably nearer Philadelphia than Rall, was, as we have seen, being closely watched by Cadwalader, whose force being largely drawn from the city had the best reasons for wishing to be rid of so troublesome a neighbor. [Sidenote: Gates sulking.] More especially in view of possible contingencies, which he could not be on the ground to direct, Washington sent his able adjutant-general, Reed,[2] down to aid Cadwalader. This action, too, removed a difficulty which had arisen out of Gates' excusing himself from taking this command on the plea of ill-health. [Sidenote: In Philadelphia.]
