Other tactical sacrifices included the widespread adoption of scorched earth policies. When King Harald of Thornmark realized he could not defend his farmlands against the advancing Vespasian horde, he ordered his own fields burned and wells poisoned. It was a decision that condemned his peasantry to famine and displacement but denied the invaders the supplies they needed to continue their march. Guerilla bands, often composed of volunteers who had lost everything, undertook the most harrowing assignments: ambushing supply caravans, destroying bridges, and assassinating enemy quartermasters. These small units operated with the understanding that they would receive no support and little chance of survival if caught. Their campaigns weakened enemy supply lines, but the personal cost was exacted in blood and brutal reprisals against civilian populations accused of harboring them.
