General Howe, upon seeing that the Rebels have taken Dorchester Heights, decides to attack. However, upon reconsideration, he changes his mind and orders his men to begin preperations for evacuation. This is an effect of the Battle of Bunkers Hill. Despite it being a “victory,” the British lost 1,000 men, as astounding number in their minds. Losing men when you are 3,000 miles from home means there is a heavy cost to replacing them. General Howe does not want to make the same mistake General Gage made (causing his eventual departure back to England) and force a head-on attack which, even if victorious, will mean heavy casualties. And so, it is decided to move on and fight another day.
John Hancock writes to General Washington about taking care of the deficit of supplies. I have the Pleasure to inform you, that the Powder Mills in this Colony are employed, and more Mills are building, which will be employed: so that I have strong Hopes we shall soon have a plentiful Supply of that necessary Article.
With Regard to Arms, I am afraid, we shall, for a Time, be under some Difficulty. The Importation is now more precarious and dangerous. To remedy this, a Committee is appointed to contract for the making Arms; and as there is a great Number of Gunsmiths in this, and the neighbouring Colonies, I flatter myself, we shall soon be able to provide ourselves without Risque or Danger.7 But we must, like other States engaged in the like glorious Struggle, contend with Difficulties. By Perseverance, and the Blessing of God, I trust, if we continue to deserve Freedom, we shall be enabled to overcome them.”
