Burn your bridges
Meaning
To eliminate all possibility of retreating from a situation, often by making an irreversible decision.
Origin
The phrase originates from a literal military tactic practiced by commanders throughout ancient history. Imagine an army crossing a river into enemy territory. A decisive, often ruthless, leader would order the bridges behind them to be destroyed. This wasn't just about preventing enemy pursuit; it was a brutal psychological maneuver for their own troops. With no path for retreat, no option to fall back to safety, soldiers were forced to fight with an unwavering conviction, knowing their only way out was forward, to victory. This stark, physical act of commitment transformed over centuries into the potent metaphor we use today for making an irreversible decision, forcing total dedication to a new path.
Examples
