Fifth Hellanan War

After the collapse of 'decisive battle tactic' employed during Fourth Hellanan War, Vhessana decided to engage Hellana in a prolonged war of attrition, hoping to use its superior manpower to wither away its military power.

  The war was waged for nearly twenty years, causing extreme loses to both sides. Hellana was brought nearly to collapse, but it was ultimately saved by Eight Eastern War.
