Please explain the meaning of this proverb-- ""Oposition to him was like proverbial fly trying to move a dunghill.""

Dear Student,

This sentence means that opposition to him was as futile as a fly trying to move a dunghill. The opposing party, compared to the fly, must have been as small and powerless to challenge something so mighty and powerful as compared to the dunghill. It refers to the situation being unnatural or impossible.
