How to say 破釜沉舟 in english?
破釜沉舟 describe an action of &quot;destroy one's own mean to retreat/escape&quot; ; the underline reasons are 1. &quot;to show determination&quot; 2. &quot;force oneself to continue&quot;
You can consider

burn one's bridges/boats

hell-bent

crossing the Rubicon


The action of &quot;burn one's bridges/boats&quot; match 破釜沉舟 almost word for word, but its main usage is to describe &quot;doing something that can't be easily undone in the future; destroy relationships or chance of reconciliation with others.&quot; the underline reason is not relevant. This phrase might describe an action similar to 破釜沉舟; Both actions cut off one's retreat route, but the reason behind &quot;burn one's bridges/boats&quot; doesn't include &quot;to show determination&quot;
Another English expression &quot;hell-bent&quot; describes the first underline reason &quot;to show determination&quot; much better

hell-bent
stubbornly and often recklessly determined or intent

&quot;crossing the Rubicon&quot; implies &quot;to past the point of no return&quot; although the action doesn't match 破釜沉舟 well like &quot;burn one's bridges/boats&quot; but it implies the underline reasons &quot;to show determination&quot; and &quot;force oneself to continue&quot; better
My conclusion is:
&quot;burn one's bridges/boats matches 破釜沉舟 in literal meaning
&quot;crossing the Rubicon&quot; matches 破釜沉舟 in its figurative meanings
