Scorched earth
A scorched-earth policy is a military strategy that aims to destroy anything that might be useful to the enemy while it is advancing through or withdrawing from a location. Any assets that could be used by the enemy may be targeted, for example food sources, water supplies, transportation, communications, industrial resources, and even the locale's people themselves.
Expedition of Dramali
Kolokotronis pursued a scorched earth policy, aiming at starving the Ottomans out. The Greeks looted the villages, burned the grain and foodstuff they could not move, and damaged the wells and springs. Dramali's army was trapped in the sweltering Argolic plain. However, Kolokotronis was not in a position to coordinate all the Greek forces, for many operated under their own leaders, refusing to follow his orders. If Kolokotronis had in fact commanded the Greek armies, and thus been able draw up a general military plan, Dramali's forces might have been completely annihilated and Nafplion would have been captured with little difficulty.
