Sources

"Colonel Stone had once again culled his District of Columbia battalions for volunteers willing to serve outside the District, and just after midnight he trotted a mounted squadron of them across the river on the Chain Bridge, well upstream of Georgetown. Galloping cross-country, he took the Virginia end of the Long Bridge from its guards, who might have set fire to it if they had heard the rumble of so many hooves from the Washington side of the bridge."

Mr Lincoln goes to war, by William Marvel

"Our regiment, as a body, did not participate in this advance, but it was ordered to hold itself in readiness to support the movement, if necessary. Fortunately, the services of the entire regiment were not needed, and the heights that commanded Washington were occupied without opposition."

Narrative of the campaign of the First Rhode Island Regiment, in the Spring and Summer of 1861, by Augustus Woodbury

"A detail of thirty men from the regiment was made today, and placed under command of Lieutenant Tower, of Company E, to operate a ferry for transporting troops across the river to Alexandria. They worked only nights, returning to camp at daylight in the morning. Company F furnished five men – Sergeant Burdick, John B. F. Smith, Andrew P. bashford, George R. White, and Peyton Randolph, all of whom had been sailors previous to enlistment in the army, and consequently wre familiar with that line of duty, and to them it was mere pastime."
