Before I answer this, could you clarify if you mean something along the lines of "Were any allied soldiers held accountable" or are you asking if there was some more overarching process similar to the Nürnberg trials but for allied officers/decision makers?

I've written before about executions of US soldiers here so in very funamental terms, the answer to your question is yes, some allied soldiers were held accountable for some things. However, before launch into a long post about something I would like to make sure I understand your question.
