When Cate Archer was preparing to sneak on-board the Lorelei at the Bremen docks, Tom Goodman instructed her to photograph the Shipping Manifest. Before she had a chance to do so, Magnus Armstrong knocked her out and had her locked in a storage room on the ship. Before Archer could escape, timed Explosives went off preventing Archer from obtaining the Shipping Manifest. She just had time to place a Beacon on the Radio before having to abandon ship.
Needing to retrieve the Shipping Manifest and the Captain's Log from the sunken vessel, H.A.R.M. sent a Submarine carrying Armstrong, Inge Wagner and several divers to the North Sea. Armstrong's instructions to the divers were to retrieve the manifest and log (as well as a bottle of Laphroaig he had in his quarters}.
Goodman and Archer were on the surface of the North Sea in a Boat also preparing to retrieve the Captain's Log and the Shipping Manifest. Archer was able to find the Shipping Manifest just before entering the cargo area full of Sharks.
