Why was Molloy not executed during the campaign?

Why was Captain Molloy not executed at that point?

One possible explanation is that Howe lacked an obvious replacement amid mounting losses and had no time to convene a court during the campaign.

Caesar still needed a commander during the running campaign. Howe may not have known whom to appoint in Molloy's place while other officers were becoming casualties. Convening a court also required time. These are proposed explanations for the delay in disciplinary action.
