1. Could you tell me which one is correct between "<i>He was fortunate in that he had many friends to help [himself/him] when he was stuck in the mire</i>?"<br/><br/>2. If both of 'himself' and 'him' fit the above sentence, what is the difference between them?<br/><br/>3. Can I say, '<i>in the mud</i>'' instead of '<i>in the mire</i>'?
