"...but if they mean to have a war, let it begin here."

These are the words that were (reportedly) spoken by Captain John Parker to the 77 militiamen who had gathered on Lexington Green on the morning of April 19th, 1775.

The weather that morning was described as "fair, windy and cold".

Militia units and Minutemen had been gathering since the early hours of the morning when riders Paul Revere, William Dawes and Samuel Prescott spread word of the British expedition leaving Boston to seize the colonists' stores of weapons and powder.

What would happen over the course of the next few hours would change the world forever.
