Being banished from Denmark to England, Hamlet observes Fortinbras marching his troops from Denmark. As he questions the meaning of the current War he inquires in the Captain that the Poland is being attacked by the Norwegians over patches of land whereas Rosencrantz and Guildenstern  are talking about the fact that Norwegians and Poles are willing to die over land worth not much. Hamlet, while on the boat journey had thought strongly about the happenings and doings and what he should do about them yet he cannot do anything with his exile. I can see that Hamlet is using this time to look at his inventory and think about his next plan as he is exiled and needs to find his way to get back at his Uncle.
