Misinformation significantly affected the planning of the Battle of Bunker Hill by misleading American commanders about British intentions and troop movements.

Reports regarding British movements and reinforcements frequently contained inaccuracies, confusing colonial leaders regarding the strength and strategy of the enemy. This misinformation hindered the organization of defenses and the coordination of efforts among the different militias. Consequently, American commanders failed to recognize the urgency of strengthening their positions the night before the battle. Ultimately, the effects of this misinformation added to the complexities of the engagement, affecting both tactics and the overall dynamics of the conflict.
