How much of Wales do the Yorkists control? Is anyone supporting the queen?
I wonder if the addition of his children to the House of Lords will mean anything.
Makes him a lot more attractive a bet because the succession is secure and in time, the king will have sons and later brothers who are all supportive and powerful Lords in their own right.
He's basically doing exactly what he should do just before triumph, promise a lot of rewards to his key supporters.
He may also keep up such rewarding with later good behaviour from current uncertain, neutral or less hostile enemies, as there is much of Wales, Ireland and even Scotland and France to carve up yet.
