Nobody Important

Nobody could have known that the Evil Ones would attack so suddenly from the North. They came with fire and folly, mounted on wild beasts, and the poor Underlings, who were very much undersized and unprepared, cried out for help across the Western Lands. They tried to broadcast the terror to the world and the Higher Elders and Wise Chieftains devised plans to strike back. As the war grew and grew the innocent Underlings watched in horror, hoping for someone to save them. One of those Underlings was Nobody Important (yes that was his actual name), and he came up with an unrealistic plan to stop the Evil Ones.What was this unrealistic plan and how could somebody named Nobody Important bring an end to the war?
