Gray113: The Carthage had perfectly valid reasons for being at Neptune. It was a combat ready vessel charged with protecting the station until ordered to retreat. Lopez was ordered to retreat. She refused to obey that lawful order, which , if the military code of justice of the GTVA is anything like US military's one, is punishable by the death penalty if in a time of war. It wasn't even a tough assignment, and if she had followed orders, the Carthage would have gotten away just fine.
The GTVA isn't some touchy-feely Star Trek Federation where good intentions can get you acquitted of pretty much anything.
TheDemon: I didn't capture any corvettes. If you did, then they'll probably be treated just like every other captured Tev warship.
