Thomas Machin on the Firing at Lexington

On 9 August 1775, Jedediah Preble (1707–1784, shown here) was visiting Cambridge.

A veteran of the wars against the French, he had been the Massachusetts Provincial Congress’s first choice to command its forces back in October 1774, but turned down the job on account of his age and health.

During that visit Preble wrote in his diary: “This morning met with a man that deserted from the regulars this day fortnight, as sensible and intelligent a fellow as I ever met with.”

A fortnight, or fourteen days, before was 27 July. There was one man who deserted from Boston around that date, remained with the Continentals, and was praised for his intelligence by men on both sides: Thomas Machin, captain in the American artillery from 1776. So I believe Preble recorded the former private Machin’s observations on the start of the war.

Preble wrote:

He was at Lexington fight. He says he came out with Lord Percy, and that he asked a young fellow of his acquaintance who fired first.

The soldiers when they first came where the Provincials were, one of them flasht his piece, on which a regular officer fired and swung his gun over his head, and then there was a general fire. They had 75 killed and missing, 233 wounded.

Alas, the antecedent for “one of them” is ambiguous: “soldiers” or “Provincials”?

Machin’s informant certainly blamed some “regular officer” for aggravating the situation. On the other hand, this version of events doesn’t have Maj. John Pitcairn or other officers ordering the redcoats to fire, which became the official provincial line soon after the battle.

There are further considerations. Machin’s information was secondhand, and he may have felt pressure to tell Americans what he thought they wanted to hear. Nonetheless, these comments ring true as a British enlisted man’s perspective: What did officers expect their soldiers to do when one of them was firing his gun and waving it around?

Preble went on:

He was also at Bunker’s Hill, where there was killed and died of their wounds 700, and 357 wounded that recovered. He took the account from Gen’l Robinson [actually James Robertson]. He says before he came out there died eight men of a-day, one day with another, and that they could not muster more than 6000 men.

Again, we know from Gen. George Washington’s files that Machin had brought out those casualty figures, as well as drawings of the British fortifications. He must have planned his desertion carefully.
