We have a request to escort the next trade convoy that is expected to arrive from Algiers. Apparently they were attacked by pirates along the way and their current escort ship suffered heavy damage. So, we need you to provide some support.
Go find out when they arrive at the port office and then rendezvous with them.
Are you reinforcements for the guild's frigate fleet? You're late! An express delivery from the trading ship fleet just arrived. The frigates were annihilated and the trading ships captured. That being the case, this is a battle for revenge. We make haste to wipe the enemy out before they get away!
