I understand it happened more than once where a general arrived by sea and shortly after landing ordered the ships to be burned, so that retreat would never be an option.
Which military commanders/generals did this, and under what circumstances?
EDIT: From searching online, I've found : Agathocles of Syracuse in 310 BC, Emperor Julian in 363, William of Normandy in 1066, and Cortez in 1519; I don't if any of these are accurate.
