The Battle of Bunker Hill highlighted the innovative use of trenches and fortified positions, which became a crucial aspect of military strategy.

American forces, primarily composed of militia, constructed defensive works on Breed's Hill, allowing them to effectively withstand multiple British assaults. This tactic demonstrated the advantages of entrenchment in combat, enabling smaller, less experienced troops to inflict significant casualties on a larger, more disciplined British army. The success of these defensive strategies at Bunker Hill influenced future military engagements, emphasizing the importance of preparation, fortification, and the effective use of terrain in warfare, especially in the Revolutionary War.
