The Battle on Doshan involved clashes between the Imperial forces and the native Trandoshans. Due to its significance, the 501st Legion was deployed.
The 501st Legion began by securing strategic locations along the Doshan landmass's equator. Subsequently, Negastrike platoon traveled via Imperial transport boats towards a fortified Trandoshan position situated near the Arakka waterway's mouth. They successfully destroyed the enemy's defenses using repeating blasters and thermal detonators. However, the platoon was then ambushed by a Trandoshan raiding company concealed beneath the algae mats of the waterway.
To minimize casualties during the landing, Negastrike platoon deployed jumptroopers to divert the Trandoshan fire, allowing the main force to reach the shore. Upon arrival, the Incinerator troops saturated the shoreline with a chemical spray while the Trandoshans were engaged with the jumptroopers. They then ignited the spray with blaster fire, resulting in over a hundred Trandoshans being burned alive within the ignited algae mats.
Negastrike Platoon's actions successfully repelled the Trandoshan counterattack. Furthermore, the platoon sergeant of Negastrike was commended by Darth Vader, who described his actions as "notable." The Rebel Alliance only became aware of the battle after its conclusion, with General Carlist Rieekan lamenting their failure to assist the Trandoshans.
