How am I supposed to know what was I going to do without knowing what happened during the war? If the internet was still up I would probably try to find someone but if it was down I would probably have a large collection of the internet archived. If the war happened tomorrow, right when I woke up, and ended at the end of the day then I would probably try to find all the necessities I needed to live. So, it depends on the context of the war and how long it lasted. If during the time it happened and it seemed very grimed then I would have taken the precautions to help increases the survival later on.
