William Walker (filibuster)
William Walker was an American physician, lawyer, journalist, and mercenary. In the era of the expansion of the United States, driven by the doctrine of "manifest destiny", Walker organized unauthorized military expeditions into Mexico and Central America with the intention of establishing slaveholding colonies. Such an enterprise was known at the time as "filibustering".

On October 12, 1856, during the siege of Granada, Guatemalan officer José Víctor Zavala ran under heavy fire to capture Walker's flag and bring it back to the Central American coalition army trenches shouting "Filibuster bullets don't kill!".
