The Battle of Bunker Hill in 1775 ended in defeat for the American Revolutionary forces. Yet, in time, it came to take on the appearance of a Pyrrhic victory for the British. Despite losing the battle, the Americans were nonetheless able to inflict quite serious losses upon the British. Strategically, Bunker Hill was undoubtedly a setback for the colonists, but it showed that their method of fighting could potentially cause huge damage to British troops and their morale. The mood of the British in the aftermath of the battle was succinctly summed up by one of their generals named Henry Clinton:

A few more such victories would have shortly put an end to British dominion in America.

It was now abundantly clear to both sides that the war would be long, bloody, and hard. The British soldiers were paid to fight and had no connection with this strange and distant land. The Americans, however, were fighting on home soil for a cause in which they passionately believed. Nearly two decades before the French Revolutionary Army achieved a stunning victory at Valmy, the Americans had already harnessed the power of revolutionary fervor in the heat of battle. They were not successful this time, but the genie of revolutionary consciousness was now out of the bottle. There was very little that the British could do to put it back in again.
