In the previous post, I asked what you would do as a general (Cornwallis), December 27, 1776. You command 30,000 troops, some 12,000 at Princeton of at total 50,000 against Washington’s 3500. Washington is camped 12 miles to the south just outside of Trenton with a majority of his men scheduled to leave in three days when their enlistments expire.

In fact, what Cornwallis did, is what every commenter recommended. He attacked at Trenton, and lost New Jersey. Cornwallis left 2-3000 troops at Princeton and marched south. Despite fallen trees, swollen rivers, destroyed bridges — all courtesy of Washington’s men –Cornwallis reached Trenton and attacked. By the time he got there, 2000 of Washington’s men had left, partially replaced by untrained militia. After a skirmish, Washington set up 400 militia to keep the fires burning, and without telling them where he was going “Fall back if the British attack”, he took the rest of his forces east, across frozen fields and swampland, then north to Princeton along the Quaker-bridge road. He later said the reason was to avoid looking like a retreat.

He split his forces just outside of Princeton, and a detachment, led by Hugh Mercer and 350  regulars had the first battle as they ran into the 17th and 55th British regiments as they prepared to escort supplies to Trenton. The British commander, Lt.colonel Mawhood, seeing how few men he faced, sent the 55th and most of the supplies back to Princeton, and led his men to shoot at the Americans from behind a fence. Mercer’s men fired back with rifles and cannon, doing little. Then, the trained British did what their training demanded: they rose up and charged the rebels with fixed bayonets. Mercer, having no bayonets, called “Retreat!” before being stabbed repeatedly, see painting. Mawhood’s men seized the cannon, turned it on the fleeing remnants of Mercer’s men.

General Mercer defeated at Princeton, as Washington shows up.

It looked like a British victory, but then General Nathaniel Greene (the fighting Quaker) showed up with several hundred Pennsylvania militiamen. The militiamen had never seen battle, and many fled, after shooting into the British lines with rifles and another cannon and grape-shot. At this point it looked like a draw, but then, Washington himself joined the battle with two brigades of regulars: Hitchcock’s 253 New Englanders and Hand’s 200 Pennsylvania riflemen.

Washington managed to rally the fleeing Pennsylvanians; “Parade with us, my brave fellows! There is but a handful of the enemy and we will have them directly!” And Mawhood, now without most of his officers, ordered a last bayonet charge and fled down the Post Road to Trenton. Washington rode after for a bit “It’s a fine fox chase, my boys!”

James Peale, 1783. John Sullivan and his forces at Frog Hollow. Battle of Princeton

The rest of the British along with Mawhood, met the rest of Washington’s men, lead by John Sullivan, at a place called Frog Hollow, near where Princeton Inn College (Forbes College) now stands. The Americans opened with grape-shot and the British put up little resistance. Those who did not surrender were chased into town, taking refuge in Nassau Hall, the central building of the university. Alexander Hamilton’s men (he’d been rejected by Princeton) took special enjoyment in shooting cannon into the building. A hole remains in the college walls and a cannonball supposedly decapitated a portrait of George II. About then the New Jersey militia broke in a door, and the British surrendered.

Washington had captured, killed, or destroyed most of three English regiments, took a wagon train of supplies, and left going north following a bit of looting. “Loyalists” were relieved of coins, liquor, shoes, blankets. They ate the breakfast prepared for the 40th, and were gone by 11 AM, heading north — to where?. Cornwallis returned before noon “in a most infernal sweat — running, puffing, blowing, and swearing.” His men looted the town again, but now what?

Was Washington headed to New Brunswick where a handful of British soldiers guarded Cornwallis’s supplies and a war chest of £70,000? He didn’t go directly, but perhaps by a circuitous route. Cornwallis went straight to New Brunswick and jealously guarded the place, its money and supplies. Washington meanwhile ran to safety in the Watchung Mountains outside Morristown. Cornwallis’s 17th claimed victory, having defeated a larger group, but Cornwallis gave up Princeton, Trenton, and the lives of the New Jersey loyalists. Rebels flocked to Washington. Loyalists were looted and chased. Hessians were shot in “a sort of continual hunting party.” Philip Freneau expressed the change thus:

When first Britannia sent her hostile crew; To these far shores, to ravage and subdue, 

We thought them gods, and almost seemed to say; No ball could pierce them, and no dagger slay.

Heavens! what a blunder—half our fears were vain; These hostile gods at length have quit the plain.

Robert Buxbaum. December 21, 2016. So now that you know what happened, what SHOULD Cornwallis have done? Clearly, it’s possible to do everything right militarily, and still lose. This is an essence of comedy. The British had a similar Pyrrhic victory at Bunker Hill. I suspect Cornwallis should have fortified Trenton with a smaller force; built a stockade wall, and distributed weapons to the loyalists there. That’s a change in British attitude, but it’s this dynamic of trust that works. The British retreat music, “the world turned upside down“, is a Christmas song.
