Chapter 11: The Sea Fortress is the eleventh chapter of Valkyria Chronicles 4. The combat mission in this is Maritime Infiltration.
We have our next mission
"Your target is Fort Garsbruck's artillery. Captain Wallace, you'll be leading the drop team in via hot air balloon. You won't be at liberty to set up camp, so choose your teammates judiciously. I suggest you take Lancers with you. They'll make short work of the cannons. Meanwhile, the Centurion will continue advancing at a steady pace. That's why it's vital you destroy their artillery before the Centurion is in range. Once that's done, the drop team will have to escape the fort as quickly as possible. We'll send in an extraction team to help. Lieutenant Victor will lead the extraction team, so she cannot join the drop team."
Location: Fort Garsbruck
Description: Infiltrate Fort Garsbruck and destroy its artillery. Minerva Victor will be unavailable. The mission will end in failure if Claude is defeated, or if it takes too many turns for the team to disable the two sea fortress cannons.
"We realize how dangerous this mission will be, so I wish you and your squad the best of luck."
