Here is an important excerpt:

"

”[A]t 5 o’clock we arrived [in Lexington], and saw a number of people, I believe between 200 and 300, formed in a common in the middle of town; we still continued advancing, keeping prepared against an attack through without intending to attack them; but on our coming near them they fired on us two shots, upon which our men without any orders, rushed upon them, fired and put them to flight; several of them were killed, we could not tell how many, because they were behind walls and into the woods. We had a man of the 10th light Infantry wounded, nobody else was hurt. We then formed on the Common, but with some difficulty, the men were so wild they could hear no orders; we waited a considerable time there, and at length proceeded our way to Concord.”[51]

— Lieutenant John Barker, 4th Regiment of Foot"

Notice the time? 5 pm. In my dream we have 4:24 pm. That's pretty close.
