Why were the hills in the Battle of the Bunker Hill so important?

The location of an area has always been an important factor in fighting a war. In the 1700s and in the 1800s, having control over a hilly area was usually an advantageous position for whoever had that position. In the Battle of Bunker Hill, this was especially true. Bunker Hill is a hill that overlooks the harbor in Boston. The colonists had control of this hill. The British, who were better equipped and supposedly better trained and to fight a war, should have been able to control this area. However, since the colonists had control over this hill, the British found it very difficult to take it. They tried three times to capture Bunker Hill. They failed the first two times. The only reason why they succeeded on the third try was because the colonists ran out of ammunition. The difficulty the British had in taking this hill gave the colonists the confidence they needed to believe they could fight the British. It also showed the importance of controlling strategic locations in war, especially the hills in those days.
