Surrender is the cessation of fighting by soldiers, naval craft, nations or other combatants and their eventually becoming prisoners of war, either as individuals or when ordered to by their officers. A white flag or handkerchief is a common symbol of surrender, as is the gesture of raising one's hands empty and open above one's head. When a tank commander is surrendering, the tank's turret should be turned opposite the direction of the opposing forces. Normally, a surrender will involve the handing over of weapons; in European warfare of earlier centuries, the commanding officer of a surrendering force would specifically offer up his sword to the victorious commander. Flags and ensigns are hauled down or furled, and ships' colours are struck to signal a surrender.
When the parties agree to terms, the surrender may be conditional, i.e. if the surrendering party promises to submit only after the victor makes certain promises. Otherwise it is a surrender at discretion (unconditional surrender); the victor makes no promises of treatment other than those provided by the laws and customs of war — most of which are laid out in the Hague Conventions (1907) and the Geneva Conventions. Normally a belligerent will only agree to surrender unconditionally if completely incapable of continuing hostilities.
The Third Geneva Convention states that prisoners of war should not be mistreated or abused. United States Army policy, for example, requires that surrendered persons should be secured and safeguarded while being evacuated from the battlefield. Similar regulations exist in most modern militaries.
