Writing the Second Draft of History with Gen. Heath

Another of the Massachusetts Historical Society’s ongoing crowd-sourced transcription projects is Gen. William Heath’s manuscript diary.

When Heath wrote his memoir, published in 1798, he went back to this document as his source. That book is in day-by-day journal form.

The entries for 9 Oct 1776, 250 years ago today, show how he developed his history.

Heath’s diary entry, as newly transcribed:
Early this morning Three ships Two of 40 Guns and one Frigate, With Two, or Three Tenders Stood up the north River, They were Briskly Cannonaded from Mount Washington and Fort Constitution, They However Passed our works & Chevaux De Frise,

our Gallies Small Craft, and Two Large Ships Stood on before them, The Two Ships were Run on shore nears Philips’s mills, and Two Gallies near Dobbs’s Ferry,

The Enemy took Possession of the Two Gallies and got them off, one Boat Landed and Plundered a Store, (Stove the Cask) & set it on fire, but our People Extinguished it,

Colo. Sargent has marched for that Place, with 500 Infantry and 40 Light Horse, Capt. Horton with 2 twelve Pounders, and Capt. Crofts with a Howtzer

the Enemy also took a Schooner Load,d with Rum Sugar Wine etc, and Sunk a Sloop which had on board the machine for blowing up their Ships, a Contrast this to Sink that, which was to Blow them up —

our Division being under arms on the alarm were marched Down over the Broken Ground in front of our Post
The day’s entry in Memoirs of Major-General Heath:
Early in the morning, three ships, two of 40 guns, and one frigate, with two or three tenders, stood up the North River. They were briskly cannonaded from Fort Washington and Fort Constitution. They however passed our works and the chevaux-de-frise; the American galleys, small craft, and two large ships standing on before them.

The two ships were ran on shore near Phillips’s mills, and two of the galleys near Dobbs’ Ferry. The enemy took possession of the two galleys, and got them off. A boat landed a number of men, who plundered a store, stove the casks, and then set the store on fire, and left it. The Americans soon extinguished the fire.

Our General ordered Col. [Paul Dudley] Sargent, with 500 infantry, 40 light-horse, Capt. [Jotham] Horton of the artillery, with two 12 pounders, and Capt. [Edward] Crafts with a howitzer, to march immediately, with all possible expedition, to Dobbs’ Ferry.

The enemy took a schooner loaded with rum, sugar, wine, &c. and sunk a sloop, which had on board the machine, invented by, and under the direction of, a Mr. [David] Bushnell, intended to blow up the British ships. This machine was worked under water. It conveyed a magazine of powder, which was to be fixed under the keel of a ship, then freed from the machine, and left with clock-work going, which was to produce fire when the machine had got out of the way. Mr. Bushnell had great confidence of its success, and had made several experiments which seemed to give him countenance; but its fate was truly a contrast to its design.

Our General’s division was formed in line, with its advance, reserve, flank-guards, and artillery, all in order of battle, when they were moved down over the different grounds, which it was supposed might be the scene of action. Some of this ground was very broken, and there were many fences. These afforded frequent opportunities for the troops to break off and form; for the pioneers to open avenues, &c. and for the whole to become acquainted with every part of the ground, and the best choice of it, if suddenly called to action.
Heath made sure he appeared in his book, as “our General,” as an active participant, issuing orders and strengthening the forces under his command.

He also took the opportunity to add more detail, such as the backstory of David Bushnell’s submarine.

This entry doesn’t reveal any significant information that Heath left out of his book. But now that the whole diary is digitized and transcribed, folks can look for those details.
