April 19, 1775:
By day's end, 49 colonists were dead, 39 were wounded. British troops reached Boston with 73 dead and 174 wounded. "Whoever looks upon them as an irregular mob will find himself much mistaken," wrote a British commander about the colonists; "they have men amongst them who know very well what they are about."
