The story is told in the form of a letter of pleading to a court deciding the fate of the former commander of a great allied space fleet. He starts the letter by describing that their final defeat was due not to the inferiority of their forces, but their superiority.

When the war opens, the allied forces have a great advantage both in number of spaceships and the power of their weapons. At the Battle of the Five Suns the enemy does surprisingly well, although ultimately losing. Spooked, the allies confer with their new Chief of the Research Staff, Professor-General Norden. He states their existing weapons have reached the limits of the potential and begins development of terrifyingly powerful new weapons.

The first of these is repeatedly delayed, and the allies pause their attacks while they wait for their ships to be fitted with the new missiles. The enemy uses these delays to capture several former allied systems. Instead of simply counterattacking with their current weapons, Norden develops still newer weapons that will make up for these losses. Each is temporarily successful, but each invariably leads to insurmountable problems and further losses.

The story ends with the author admitting their defeat, but begs the court's favour as he can no longer be held responsible "for my future actions if I am compelled any longer to share my cell with Professor Norden, late Chief of the Research Staff of my armed forces."
