The terrain during the Battle of Bunker Hill favored the American forces, primarily due to their defensive positions on Breed's Hill.

The elevated terrain provided the Americans with a strategic advantage, allowing them to effectively monitor and engage British troops as they advanced. This positioning maximized their firepower while reducing their vulnerability. As a result, the colonial militias were able to inflict considerable casualties on the British during their frontal attacks. Furthermore, the Americans utilized the natural landscape to strengthen their defenses, improving their capacity to withstand the more well-equipped British forces. In summary, the tactical use of the terrain was pivotal in shaping the dynamics and outcome of the battle.
