Ulric Tagge's second, third, and fourth battlecruisers (Captain Wermis's battlecruiser in the lower pic foreground).
General Tagge was on-board a battlecruiser with sleek armor, when meeting with his older brother Orman to discuss the plot to wrest power away from Darth Vader. Later on, the general switched between several vessels stationed at the blockade of the Gordian Reach.
