" every man for himself "

 [ "Every Man for Himself" ]

1: British military origin. In Armed Forces terms, this formal order is a specific command sometimes issued in a case where the strategic situation has become hopeless, the collapse of a force is imminent, and there is no chance of relief. Once given, the order suspends certain aspects of military discipline, allowing each individual to surrender, flee, or continue fighting independently according to their individual circumstances, without regard to previous battle orders. It also means that the parent force is declaring itself free of any duty to continue to provide further supplies, medical aid or tactical support for the forces who receive this order.

  * e.g.,  ... The battalion was down to only a dozen surviving troops, and with the enemy closing in, the order was given: "Every Man for Himself!"
