Charles XII's distant campaigns weaken central command

Swedish performance at sea deteriorated while Charles XII was trapped in Ottoman territory. In a state organised around royal direction, the ruler had to remain in contact with its political centre. The advance toward Moscow therefore created a problem beyond the fighting itself: it separated the king from the government he needed to direct. He had few generals and admirals he trusted to act for him, while experienced officers were ageing and dying. That dependence on Charles's presence gave Peter I an advantage in sustaining central direction.
