Answer: FAMILIAR W TERRAIN, GUERILLA TACTICS
Step-by-step explanation:
Familiarity with the terrain: The American militia forces were largely composed of local farmers and other citizens who were familiar with the terrain around Concord. This knowledge allowed them to use the landscape to their advantage, setting up ambushes and other defensive positions that were difficult for the British troops to overcome.
Guerilla tactics: The American militia forces used guerrilla tactics, such as hit-and-run attacks, to harass and weaken the British troops. These tactics allowed the Americans to avoid direct confrontation with the well-trained and well-equipped British forces, while still inflicting significant casualties and disrupting their operations. Additionally, the American forces were highly motivated and fighting on their own territory, which gave them an added advantage.
