It was all very confusing, the reasons for the war, the nature of the enemy. The Yucconae had been contacted on one of the outlying planets of Proxima Centauri. At the approach of the Terran ship, a host of dark slim pencils had lifted abruptly and shot off into the distance. The first real encounter came between three of the yuk pencils and a single exploration ship from Terra. No Terrans survived. After that it was all out war, with no holds barred. Now though, the Yucks had made their mine fields sentient, they could seek out and destroy Terran ships. The only response was to put a human brain into a ship. The results were, to say the least, surprising to everyone. No one expected what would happen. Least of all the generals who thought up the idea. The human brain in the spaceship had ideas of his own and they did not include listening to the generals.
