3. For question 7: Washington's army positioned the newly arrived cannons on Dorchester Heights, a high ground overlooking Boston Harbor and the British-held city, which would have allowed them to fire on British supply ships and the city itself, threatening their supply line and position.
4. For question 8: The British Commander during the Siege of Boston was General William Howe, who took over from Thomas Gage in late 1775.
5. For question 9: General Howe withdrew British forces on March 17, 1776, evacuating the city of Boston and sailing to Halifax, Nova Scotia, to regroup, after being threatened by the American artillery on Dorchester Heights.
