You do realize that everyone gets their taxes in gold, so long as they are in the realm, right?
I am not sure what tax rates are there but it is the lack of gold that suggests he had performed financial actions to me. Say he gains a lowly 50 gold per week and he has not spent a penny on troops the whole time (100 days):
100 days/7 = 14.29 weeks
14.29 weeks * 50 gold per week = 714.5 gold earned
I would assume that a noble with no troop expenses to have more than the 450 he did. He put that money somewhere. Into training, to his family, to other nobles, i have no idea. But he took the time to do that and not to respond.
