Original prompt & settings (JSON) ↗The first fight lasted less than three minutes and left eight Lexington militiamen dead — and nobody has ever established which side fired the shot that started it.
About 5 a.m., 19 April 1775: Lexington Green
On 19 April 1775, about 700 British regulars under Lieutenant Colonel Francis Smith marched from the Boston area toward Concord to seize and destroy colonial arms and supplies, on secret orders from the royal governor, Thomas Gage.
At about 5 a.m. they met 77 members of Captain John Parker's militia on Lexington Green. Parker ordered his men to disperse, an unidentified shot was fired, and British volleys left eight militiamen dead and ten wounded. No reliable evidence identifies who fired first; British and provincial accounts conflict.
North Bridge and the order to return fire
At Concord's North Bridge, approximately 400 provincial soldiers advanced against approximately 96 regulars. After the British fired, Major John Buttrick ordered a return volley that killed or mortally wounded three regulars and wounded nine more.
Smith began withdrawing from Concord around noon. Militia converged along the road and fought the British column through Lexington, Menotomy and Cambridge — a running battle stretching about 16 miles along the Bay Road, not a clash confined to two village greens.
By nightfall: a siege instead of a crisis
Nearly 1,000 reinforcements under Brigadier General Hugh Earl Percy rescued Smith's exhausted detachment at Lexington, and the combined force fought its way to Charlestown, reaching safety around 7:30 p.m.
The day cost the British 273 casualties — 73 killed, 174 wounded, 26 missing — against 95 colonial casualties. That night most provincial troops moved to Cambridge while wounded regulars were ferried from Charlestown into Boston, and siege operations developed immediately.

What the sources leave uncertain
- No reliable evidence identifies who fired the first shot on Lexington Green. British and provincial accounts conflict.
- Several colorful sayings and individual combat stories were recorded decades afterward and should be labeled as tradition rather than treated as contemporary testimony.
