In 1066, Harold of England put the Saxon fleet to sea to deter an assault from Norway or Normandy against England. However, when harvest-time came, the sailors went home to their fields and the way was open for the invasions that doomed Anglo-Saxon England.
What if Harold kept the fleet at sea somehow? Perhaps he recruits a good labor force to look after the sailors' crops so that they can keep patrolling without letting their harvest go to waste. How long would the Saxon fleet need to keep patrolling the Channel before Harald Haardrada of Norway and William the Conqueror get tired of waiting and either attack or give up?
