“The attempt had for several weeks been expected”

In the first half of the nineteenth century, American historians continued to write about the start of the Revolutionary War, of course.

But those authors didn’t dig into the question of whether someone close to Gen. Thomas Gage had leaked his plan for a march to Concord, as hinted by the passage from Charles Stedman’s book that I quoted yesterday.

Around the fiftieth anniversary of the event, there was a back-and-forth between Elias Phinney of Lexington and Ezra Ripley of Concord over where militiamen returned the first significant fire at the redcoats. That dispute produced eyewitness testimony from aged veterans, revealing that both towns were on alert well before the Patriot alarm riders from Boston arrived because of previous reports about British activity and the sight of army officers on horseback.

Likewise, James T. Austin’s Life of Elbridge Gerry (1828) offered evidence that members of the committee of safety were watching for Gage to act. It included documents confirming how the British army officers that Gage sent out to stop alarm riders actually provoked an alarm.

In his History of the Siege of Boston (1849), the Charlestown historian Richard Frothingham published Richard Devens’s description of the committee’s activity and of the lights in Old North Church as seen from the opposite shore. That account lined up well with Revere’s.

Frothingham quoted Stedman’s story but not the detail of Gen. Gage telling only one other person besides Col. Percy about his plan. Instead, he emphasized how Massachusetts Patriots had gathered multiple signs that the army was about to act even as the general considered his planning secret.

As a result, the most authoritative American historian of the time, George Bancroft (shown above), presented events this way in his 1860 History of the United States from the Discovery of the American Continent:

On the afternoon of the day on which the provincial congress of Massachusetts adjourned, Gage took the light infantry and grenadiers off duty, and secretly prepared an expedition to destroy the colony’s stores at Concord. But the attempt had for several weeks been expected; a strict watch had been kept; and signals were concerted to announce the first movement of troops for the country. Samuel Adams and [John] Hancock, who had not yet left Lexington for Philadelphia, received a timely message from [Dr. Joseph] Warren, and in consequence, the committee of safety removed a part of the public stores and secreted the cannon.

On Tuesday the eighteenth, ten or more sergeants in disguise dispersed themselves through Cambridge and further west, to intercept all communication. In the following night, the grenadiers and light infantry, not less than eight hundred in number, the flower of the army at Boston, commanded by the incompetent Lieutenant Colonel [Francis] Smith, crossed in the boats of the transport ships from the foot of the common to East Cambridge. There they received a day’s provisions, and near midnight, after wading through wet marshes, that are now covered by a stately town, they took the road through West Cambridge to Concord.

“They will miss their aim,” said one of a party who observed their departure. “What aim?” asked Lord Percy, who overheard the remark. “Why, the cannon at Concord,” was the answer. Percy hastened to Gage, who instantly directed that no one should be suffered to leave the town. But Warren had already, at ten o’clock, despatched William Dawes through Roxbury to Lexington, and at the same time desired Paul Revere to set off by way of Charlestown.

Revere stopped only to engage a friend to raise the concerted signals, and five minutes before the sentinels received the order to prevent it, two friends rowed him past the Somerset man of war across Charles river. All was still, as suited the hour. The ship was winding with the young flood; the waning moon just peered above a clear horizon; while from a couple of lanterns in the tower of the North Church, the beacon streamed to the neighboring towns, as fast as light could travel.

Quite dramatically rendered, and Bancroft skipped right over the question of whether anyone leaked Gage’s orders.
