The Origin of Breech and Breach
Both words are very old and come from Old English, but from different roots. Breach comes from Old English bræc or bryċe, meaning a breaking or fracture, linked to the verb break. It entered Middle English as breche and kept the break sense.
Breech comes from Old English brēc, which referred to leg coverings or garments for the lower body, like breeches. Over time, it shifted to mean the rear part of an object like a gun and, in medicine, a butt first birth position.
The spelling difference exists because the vowel patterns diverged in Middle English to reflect their different meanings and roots. Even though they sound the same today, their histories kept the spellings distinct to avoid meaning mix ups.
British English vs American English Spelling

There is no British vs American spelling split for these words. Both US and UK English use breach and breech the same way. The difference is not regional. It is about meaning.
What does change by region is usage frequency and context. For example, legal and news writing in all English varieties favors breach like breach of contract or data breach. Medical and historical or firearm contexts use breech like breech birth, breech loading rifle, or breeches.
