How did British musket volleys help decide the Battle of Quebec?

At the Battle of Quebec on September 13, 1759, British musket volleys were the decisive factor in defeating the French forces on the Plains of Abraham.12

Although the French army under the marquis de Montcalm began firing at the maximum effective range of their weapons, the British soldiers—composed of highly disciplined regulars—maintained their positions and held their fire. The British waited until the advancing French were less than 130 feet (40 meters) away before unleashing coordinated, devastating volleys of musketry. This disciplined fire quickly halted the French advance and forced a retreat, effectively securing the victory for the British forces led by James Wolfe.1
