Imaginative science fiction story where the shark kingdom mass the biggest sea-creature army ever assembled and launch an attack against the whale kingdoms ice fort. The sharks and their allies travel thousands of miles and lay siege to the ice fort with all their military weight hoping to destroy the whale kingdom in one decisive battle. Unexpected the shark kingdom army encounters many difficulties as they travel across the uncharacteristic regions of the ocean that stretches their food supply lines to the limit. Only a small percentage of these food supplies actually reach the army, due to endless attacks and raids by rebel, hostile and resistant sea-creatures who for whatever reason are determined to undermine the shark kingdoms desire and ambition to rule the ocean world. The main logistics problem for shark kingdom is that the longer the shark kingdom lays siege to the whale kingdoms lair, higher volumes of food will be needed into the area to feed the troops, the main risk is that this unprotected food supply could become noticed by other hungry sea-creatures as it travels on route across many none-secure regions to its destination.
