“Beset on all sides by upwards of four hundred men”

In 1770, New Hampshire governor John Wentworth appointed John Cochran (1730–1807) the official commander of Fort William and Mary in Portsmouth harbor. This was a more permanent responsibility than a militia rank, though less than the regular army.

According to an article in Loyalist Trails, Cochran was a sea captain who had settled on a farm in Londonderry, New Hampshire, with his wife Sarah and their children.

Both John and Sarah Cochran were on the fortified island on 14 Dec 1774, 250 years ago today. The evening before, Gov. Wentworth had sent a warning that local Patriots might try to take possession of the fort or its military supplies.

The Cochrans noticed an unusual number of visitors that day—men saying they’d just dropped by the island to chat, even though they’re never done that before. The couple became suspicious, and Sarah brought John his pistols.

More men arrived, kept outside by the fort’s guns. Future Continental Congress delegate John Langdon and sea captain Robert White convinced Cochran to let them in for a conversation.

Those two men told the commander they wanted to remove all the gunpowder from the fort. Cochran asked if they had authorization from the royal governor. Langdon reportedly replied that he “forgot to bring his Orders, but the Powder they were determined to have at all Events.”

In the evening Cochran wrote a quick report to Gov. Wentworth about what had happened next:

I received your Excellency’s favour of yesterday, and in obedience thereto kept a strict watch all night, and added two men to my usual number, being all I could get.

Nothing material occurred till this day one o’clock, when I was informed there was a number of people coming to take possession of the Fort, upon which, having only five effective men with me, I prepared to make the best defence I could, and pointed some Guns to those places where I expected they would enter.

About three o’clock the Fort was beset on all sides by upwards of four hundred men. I told them, on their peril, not to enter; They replied they would. I immediately ordered three four pounders to be fired on them, and then the small arms, and before we could be ready to fire again, we were stormed on all quarters, and they immediately secured both me and my men, and kept us prisoners about one hour and a half, during which time they broke open the Powder House, and took all the powder away, except one barrel, and having put it into boats and sent it off, they released me from my confinement.

To which can only add, that I did all in my power to defend the Fort, but all my efforts could not avail against so great a number.

Wentworth later interviewed witnesses, gathered depositions, and compiled a longer account. Those documents weren’t published until the 1970s. They contained more dramatic details, such as where the fort’s cannon shot had ended up: one four-pound ball “went thro a warehouse,” another “pass’d thro a Sloop,” and the third “lodg’d in an House in Kittery,” Maine.

As the attackers stormed in, Cochran found himself pushed back against a wall, his musket broken, jabbing at assailants with his bayonet. A Portsmouth sailor named Thomas Pickering jumped onto the captain’s shoulders and grabbed him by the neck. Finally the “Multitude” marched Cochran off to his house to retrieve the key to the powderhouse.

Instead, they found Sarah Cochran, who had herself “snatch’d a bayonet” and tried to rescue her husband. The crowd overpowered her and locked the couple (and perhaps their children) in the house while some went to break open the powder supply.
