I wonder if Henry is making the same mistake as Edward III. At the time it was a good idea for Edward III to make his sons royal Dukes. Edward's military command structure began with himself of course at the centre, and then members of the court acted as his generals. This included the Edwards family and he used his sons military capabilities to the fullest especially the Black Prince. You could say that Edward's rule was very personal and familial in nature.
However down the line as history showed, this became a problem for the monarchy as a whole. It may be worse in Henry's case with eight of his sons being Dukes and having multiple sons themselves.
