patriot battles 208
Laurie now tried to execute a complicated maneuver called
“street fighting,” whereby he would draw his companies into columns
of twelve lines of eight men each. The theory was that the first line
would fire and then peel off to each side and move to the rear, leaving
the second rank to fire, peel off, and so on down the length of the
column, exposing the patriots to continuous volley fire. It was an
evolution that had been developed in Britain when the army acted
as “police” putting down civil unrest. It may have worked effectively
against unarmed strikers and rioters, but the realities of battle are
not always sympathetic to complicated maneuvers carried out by
frightened and inexperienced men. Under fire, the discipline of the
redcoat front ranks collapsed, blocking the line of fire of the men
stacked up behind them. Laurie’s force was pushed back 400 yards
until it collided with units of the grenadiers Smith had sent up in
support. A bayonet charge by the grenadiers drove off the patriots,
who withdrew back across the bridge and partway up Punkatasset
Hill. Surprisingly, Parsons returned from his foray to Barrett’s farm
and recrossed the North Bridge without being molested by the militia
on Punkatasset and the whole British force reassembled in preparation
for their long march back to Boston. It was now close to noon.
Smith, sensibly, had flankers out on both sides of his column,
where, recorded Lieutenant Sutherland, “a vast number of armed men
drawn out in battalia order, I dare say near a thousand were approaching
through the trees” on the column’s right and “a much larger body drawn
up to my left,”

but as the column approached a small bridge over Tan-
ner’s Brook at Merriam’s Corner, the flankers were forced back down
to the road in order to cross with the main force, and this afforded the
militia, now massed on both sides of the road, the opportunity to close
and fire on the redcoat units as they were funneling over the bridge.
British casualties started to mount. They had gone only one mile, but it
was the prelude to a bloody running of the gauntlet that would continue
all the way back to Lexington, where a relief force of about 1,400 under
Lord Percy was waiting for them. Panicked, dehydrated, burdened with
wounded, and almost out of ammunition, the Smith force ran and stum
