Origin: Someone with their back to a wall cannot retreat any farther and must face whatever is in front of them. The phrase itself has no recorded date: it appears neither in Littré nor in the Académie française's dictionaries of 1694, 1762, 1798, 1835 and 1932, and Wiktionnaire marks its date as unknown. The scene is old, though: the Académie's first dictionary (1694) illustrates adosser (to set one's back against) with a man who set his back to the wall and so held off his attackers. Those dictionaries also have a close cousin, mettre quelqu'un au pied du mur (to put someone at the foot of the wall), listed in 1762 for leaving someone no way out. English uses the same picture in "with one's back to the wall."
