Lieutenant Colonel Smith
April 22, 1775
In the obedience to your Excellency’s commands, I marched on the evening of the 18th inst. with the corps of grenadiers and light infantry for Concord, to execute your Excellency’s orders with respect to destroying all ammunition, artillery, tents, &c, collected there.
I think it proper to observe, that when I had got some miles on the march from Boston, I detached six light infantry companies to march with all expedition to seize the two bridges on different roads beyond Concord. On these companies’ arrival at Lexington, I understand, from the report of Major Pitcairn, who was with them, and from many officers, that they found on a green close to the road a body of the country people drawn up in military order, with arms and accoutrement, and, as appeared after, loaded.
