Twilight Company's senior officers voted to elect Hazram Namir to lead the company going forward. Former Governor Everi Chalis came up with a plan to seriously damage Kuat's shipyards. The plan involved several different diversionary attacks at other production planets to lessen Kuat's defenses. The first attack would be on Mardona III, a warehouse world.</ref>
The main mega-spaceport for the transport of goods was absolutely ginormous. There were dozens of giant black and crystalline buildings that jutted out and extended deep underground. The city was mostly mechanized with only a few hundred thousand workers. The Thunderstrike launched its drop ships and fled the system. Several dozen squads of rebels began asymmetrical warfare, ambushing security teams and disabling train networks. The Empire was forced to shut down power to a five-mile underground sector, but the rebels were prepared with night vision goggles and personal respirators. Namir's squad was ambushed by spider droids, but they were easily able to push them back. Each squad was supplied with two dozen ion mines. Tram rails, junctions, and warehouse entrances were all hit. Thousands of mines were now planted throughout the warehouse planet. It would take months for the Empire to clear them all and force them to shut down the system.
The second day brought pain to the invaders. Several Imperial vehicles started sweeping through the underground warehouses, annihilating any squad they found. Namir was forced to retreat his troops back to a housing block, scattering civilians as they went. Namir listened to concerns from the worried civilians constantly. Most of his troops were either defending the barricades from periodic assaults, planting mines, or scouting for new routes. Every day the Imperials would seal off a route, but every day Chalis would find a new one through blueprints, or Brand scouted for new tunnels. The Empire couldn't use heavy weaponry, in fear of destroying their own block, and the housing block was protected from large vehicles.
By the end of the fourth day, Namir received word that Charmer's squad was ambushed by an armored worm vehicle with flame weapons and stun beams. Corbo was the only one to survive. That meant six had died in the past two days. Two teams went hunting for the worm vehicle and caught it parked at a sentry post. The crew that were not instantly shot were beaten to death by the rebels. A single grenade tossed down the hatch destroyed the vehicle. Reinforcements arrived, but the imperial lost twelve more men. Convinced that a spy was among the civilians, a contingent of soldiers found an old man with a transmitter and nearly beat him to death before Gadren intervened. They stole everything from him and forced him into the tunnels.
The Company left on the sixth day with four-fifths of the mines laid. Mardona's security forces were ready, and Namir expected a bloody withdrawal. However, a squall arrived and allowed the company to escape with only a few casualties.
The attack ended in a solid Alliance victory despite the loss of Sergeant Pol Andrissus. Carver gave a eulogy, while Chalis gave a rousing speech before the company. The ion mines harassed the imperials for several months, forcing them to redirect forces and return to the outdated trade routes.
The attack on Mardona III first appeared in the 2015 novel Battlefront: Twilight Company, written by Alexander Freed.
