XIX: The Battle of Earth explained

The Solar System's forces are on the verge of losing the battle for Earth when Arcot returns with a new weapon.

What happens

The Solar System's forces are on the verge of losing the battle for Earth when Arcot returns with a new weapon. He orders all ships to retreat within the atmosphere and then engages the Thessian fleet with devastating new technologies, including a ray-reflecting cosmium hull, artificial matter, and a space-warping magnetic field. Arcot destroys the Thessian ships one by one, culminating in the annihilation of the entire Thessian fleet near Venus using an invisible barrier of artificial matter. The chapter ends with Arcot declaring the beginning of the end and heading home.
