What metaphors are used in The Diary of Samuel Pepys by Samuel Pepys?

Pepy's notation in the diary that he was "Not willing to let him go away a conqueror", implies that the encounter between himself and this child is not a mere contest of wills, but rather a war..... a war in which one of them must be a conqueror. He, the master, cannot afford to lose even a little battle, for it might lose him the war.
