Several key commanders realized what was happening at about the same time and took various actions. Colonel Otho Williams, commander of the Maryland Brigade, had just watched the repulse of Webster and now rode over to see how his other regiment was doing. When he saw, what he did was send aides galloping to Greene and Howard with the bad news. What he said, surely something choice, is unrecorded. Colonel Howard, after quickly consulting the fallen Gunby, faced his 1st Maryland Line about and wheeled them into position to block the British from the army's rear. Colonel Webster, seeing an opportunity as the 1st Maryland's move exposed Hawes' flank, ordered his bleeding 33rd and their light infantry support back across the vale to assault the Virginians. But Kirkwood's Delaware company, and, possibly, some of Stevens' militia brigade came up beside Hawes. General Nathanael Greene gave orders to prepare for a general retreat. But things were happening much too fast for his orders to affect events already in progress.
Colonel William Washington was watching from his hilltop just south of the road. He gathered up his great roly-poly frame, swung up onto his horse, drew his saber, and ordered his cavalry to charge the Guardsmen. He led the van himself, as always. Riding with the fierce, moonfaced leader of horsemen on this day was the Virginia giant, Private Peter Francisco of the Prince Edward County militia. He was six foot eight and supposed to be the strongest man in the Commonwealth. He swung a specially forged five-foot broadsword. They thundered down the slope on their great warmblood horses, crossed the road, jumped the ditch beside it, and hit the startled Guards at a gallop. They cut and trampled their way through, shattering the ranked formations, then turned and overrode them again, going the other way. Francisco is most frequently credited with eleven kills in the action, but he only remembered four in his own pension application. One redcoat pinned the giant's thigh to his horse's flank with a bayonet. By the legend, he leaned over and, with free hand, helped the Guardsman withdraw the weapon before, with sword, he cleft him, helm and skull, down to the collar bone. Now Howard's 1st Marylanders fell on the broken British, closing with them after only one point-blank volley. Captain John Smith, after cutting down a Guardsman, was attacked by James Stuart, Guards' Colonel. Stuart lunged with his short sword, missed, stumbled over the fallen soldier, and was killed by Smith with a backhand slash. Then the colonel's batman came at Smith but was killed by another Marylander. Smith cut down one more guardsman before he was shot in the back of the head. Some of Washington's riders lingered with mounted senior infantry officers on the periphery of the fight, slashing at redcoats who tried to break out.
The swirling mass of men and horses, bayonets and sabers, moved westward, past the guns again and toward the British side of the vale, propelled mainly by desire of the surviving Guardsmen to escape the apocalyptic nightmare that enveloped them. Among some newly arrived British on the west side was Cornwallis. One of his proudest units was broken and being slaughtered before his eyes. Fearing the spectacle might dispirit others, he put a quick end to the Guards' agony. His artillery was up and he ordered Lieutenant Macleod to fire on the melee, friend and foe alike. This was done. Washington and Howard soon pulled their men back to safety, Smith's men carrying their fallen Captain. To their surprise and enjoyment, he soon revived. A pathetic remnant of the Guards fled to the British side of the ravine. No officers came back with them, carried or otherwise.
