The 700 British regulars under Lt. Col (later MG) Francis Smith that sortied out of Boston to Lexington and Concord some 250 years ago this month did so in a bewildering array of units. Smith’s force included the Grenadier and Light Infantry Companies of the 4th (King’s Own), 5th, 10th, 23rd (Royal Welch Fusiliers), 38th, 43rd, 47th, 52nd and 59th Regiments of Foot, Grenadier and Light Infantry companies of the 1st Battalion of Marines, and also the Grenadier company of the 18th (Royal Irish) Regiment of Foot.
For those keeping up at home, that’s at least 21 companies for what would today be viewed as a light battalion-sized force.
Why?
Robust and agile Grenadiers and “Light Bobs” from various regiments and Marines made up the British force that marched on Lexington and Charleston. They were typically drilled and trained to skirmish with the enemy from behind cover, provide reconnaissance, and protect the army’s flanks, whereas more traditional line infantry companies from the same regiment were of the “stand and deliver” style force that would provide massed musketry in a set-piece battle (NPS photos)
The reason for the variety was that Smith, looking to move fast, had the cream of the Britsh regiments in Boston, the elite Grenadiers and the skirmishers of the Light companies, with each of His Majesty’s regiments of foot organized into 10 companies: eight line, and two flank (Grenadier and Light). The picked men of each regiment. Smith’s main striking force would be the Grenadiers, screened and supported with the assorted Light companies.
It was a good choice, as his exhausted force would have to cover 18 miles from Boston to Concord and back, with the way back under a fierce fighting retreat, in 22 hours.
Each British infantry regiment of the time numbered 477 men in 10 companies, with each of the latter typically containing no more than 49 men: a Captain, two Lieutenants, two Sergeants, three Corporals, a Drummer, two Fifers, and 38 Privates. As basic math would have given Smith a force of well over 1,000 on paper, the discrepancy (700 marching out of Boston), shows how understrength through illness, death, and discharges the Brits were.
King George III only had a 48,647-strong Army- deployed around the globe- in 1775, organized in 46 regiments of infantry and 16 of cavalry as well as an array of independent companies and support units. Of those 46 regiments of foot, an impressive 18 were deployed to America. At the start of the war, the only regular cavalry in the Americas was the 17th Dragoons, numbering just 288 sabres in four squadrons.
In all, only 8,580 British regulars were in America at the start of the Revolution.
Facing 4,000 alerted Massachusetts militia who began surrounding Boston on the morning of 20 April- an 11-month siege that would eventually lead to the evacuation of the city by the British in March 1776- you can see how thin the King’s hold on the colony really was.
