burn one's bridges/boats, to

To commit oneself to an irreversible course of action, without possibility of backing down. The expression comes from ancient military history, when soldiers crossing a river literally burned the bridge or boats they had used in order to cut off the possibility of retreat. A cliché by the nineteenth century, the expression has invited a number of humorous twists, such as “Never burn your bridges till you come to them” (Stanley Walker, 1941). See also cross the Rubicon.
