The LDS is escorted by Codename Amber to a rendezvous with Agent Brunelle, an SOE Lieutenant who operates a large Resistance network in Ostend, Belgium. They meet in a buried boxcar near Hondschoote, France. Brunelle explains that Baker Street wants to stop civilian merchant fleets assisting Germany. They want the LDS to “make an example” of a tramp steamer and its captain. They have chosen the Nectaris, which should be arriving in Ostend shortly. Using a plan developed by Brunelle, the LDS sneaks across the Belgian border and into Ostend.
In Ostend, the LDS develops a bold plan of attack that includes an assault on the Kriegsmarine fleet stationed at the Port. Coincidentally, the raid will occur on the same evening as a large SS-Waffen gathering that will leave the streets relatively free of German patrols. Using Brunelle’s contacts, the LDS enlists the aid of several Resistance cells; the squad needs the ship’s moorings cut and their escape route prepped. When darkness falls, the attack begins.
Moving swiftly, the LDS overwhelms a Kreigsmarine observation point that guards the opening to the channel. Agent Belgarde uses the cleared observation point as a sniper platform, covering the squad as they board the Nectaris. The assualt team finds the Captain in his quarters, enjoying the radio and a pipe. They quickly overwhelm him and prepare to deliver their message when the Captain bargains for his life. He claims that SS officers in Oslo, Norway hired him to smuggle goods past their own German comrades. He surrenders the cargo to the squad but attempts an escape, forcing Agent Céline to shoot him. Agent Brasseur discovers that the SS were smuggling several kilograms of small blue gemstones.
Meanwhile, Agent Belgarde is forced to kill several crew members to stop them from discovering the assault team. He advises that the squad stop their original plan to save the crew and get the ship moving. The assault team captures the bridge and Céline plants explosives in the engine room. On the way back to the bridge, he signals the Resistance to cut the moorings and the Nectaris is on its way.
Agent Dubois steers the Nectaris out of the commercial basin and into the main canal. He points the massive tramp steamer at the Kriegsmarine fleet and locks the wheel into place. The assault squad then makes its way to the deck as the cruisers and destroyers of the German fleet open fire on the approaching ship. Under a massive firestorm, the assault team jumps into the river and swims into the carefully prepared storm drains. The Nectaris, now a burning hulk that remains afloat, rams into the side of a Nazi cruiser, cleaving it into two. Both ships burst into flames and sink to the bottom of the river. The wreckage traps the Kriegsmarine fleet in the Port, taking them out of the German war effort for weeks.
Agent Belgarde abandons his gear and makes his way to a safe house. The assault team barely survives the terrible swim through the storm drains but arrive at a pump house. Everyone stays where they are for twelve hours while panic and chaos engulfs the Port of Ostend. After an SS soldier discovers the team in the pump house, they decide to move through the dangerous streets to the safe house. The team is stopped by Heer soldiers, who rob them of their valuable and send them on their way. Fourteen hours after the assault began, the LDS is together again and safe. It takes a couple of days to return to The Park near Langres.
Days later, the LDS watches from a hilltop as an SS battalion with over 500 men makes its way towards Langres …
