Mission to Agamar (2 BBY)

In 2 BBY, Captain Rex and the Spectres undertook a mission to the planet Agamar to obtain proton bombs from a Separatist supply ship. However, they were captured by a holdout of the Confederacy of Independent Systems by still-functioning battle droids led by the super tactical droid Kalani. The droid general wished to end the Clone Wars on his own terms, and challenged the rebels to a battle that would decide the victors, taking Garazeb Orrelios hostage. Led by Rex, Ezra Bridger and Kanan Jarrus eventually managed to overpower the droids and confront Kalani, but Imperial forces suddenly arrived and attacked the Separatist supply ship. The rebels and droids came to the conclusion that the Empire was the real victor of the Clone Wars, and decided to unite to get a victory of their own. They used the droids to distract the Imperial forces like their AT-AT walkers in order to cripple them with proton bombs, which allowed them to escape in several Separatist Sheathipede-class transport shuttles. The Spectres kept their shuttle as a replacement for their lost shuttle, the Phantom.
