The Battle of Malastare, one of the fiercest battles of the Clone Wars, took place on the planet Malastare. The Confederacy of Independent Systems attempted to deplete the Galactic Republic‘s fuel supply by sending a massive army to conquer the world. The army was deactivated by a prototype electro-proton bomb.

In 21 BBY, after an extended period of battle, the Confederacy was on the verge of capturing Malastare, which would subsequently grant the Confederacy access to the fuel reserves on the planet. In response to the Separatist attack, Chancellor Palpatine authorized the Republic forces to use the electro-proton bomb, a superweapon designed by Doctor Sionver Boll that was capable of disabling armies of droids and vehicles within its electromagnetic blast radius. However, General Windu had initially feared that the weapon could potentially affect the planet’s ecosystem, but the pair eventually came to an agreement at the Chancellor’s urging.

As the massive droid army, under the command of TN-123, approached on the plain near the royal palace, the droid gave the command to open fire and thousands upon thousands of battle droids started to fire on the outnumbered Republic forces of. The Separatists also launched several squadrons of Hyena-class Droid Bombers and Vulture-class droid starfighters to bomb the Republic’s forces. Dug rail guns and Dug debris loaders shot down many of them, but this had the unforeseen result of several All Terrain Tactical Enforcers being destroyed by crashing starfighters.

The Republic then sent out its BTL-B Y-wing starfighter/bombers escorted by ARC-170 Starfighters. The hundreds of Armored Assault Tanks attempted to shoot them down, but were unsuccessful. A group of Dug warriors attempted to charge the enemy lines, but were obliterated by DSD1 dwarf spider droids. Meanwhile the clone troopers managed to hold the line, despite heavy casualties.

The Y-wings finally reached the drop site and the boss were released. The bomb initailly created a large explosion that further grew into an even larger electro magnetic field that obliterated the whole army and caused all electronics to shut down.
