The Erasmus’s Secret Transfer to Yokohama

The Erasmus’s Secret Transfer to Yokohama is a coordinated nighttime extraction that puts Blackthorne’s ship back under his command and shifts the escape from guarded streets to open water. Before dawn, Naga leads Blackthorne, Yabu, Uraga-noh-Tadamasa, and six samurai through Osaka Castle’s controlled passages and out toward the Erasmus wharf. The operation depends on secrecy, trusted escorts, and a second vessel ready to tow the ship; its success is measured not by a battle won, but by the jetty falling away as the two ships feel their way into the harbor stream.

Route Through the Castle

Just before dawn, a side gate’s portcullis lifts without a sound. Ten men cross the narrow drawbridge, and the iron grille closes behind them. The sentries on the far side deliberately turn their backs, allowing the party to pass without challenge. Naga leads, with Yabu beside him, through side turnings, staircases, and little-used passages. At patrols and sentry posts, he displays a silver cipher; the guards let the party through without questions. The route is covert, but not improvised: its progress depends on a signal that makes passage possible inside a fortress whose guards remain alert.

The party reaches the main south gate, the only way across the castle’s first great moat. A company of samurai is waiting there. They surround Naga’s group, screen it as it crosses the bridge, and continue with it toward First Bridge. Near the castle, the men keep to the shadows cast by the many flares; after crossing the bridge, they turn south and disappear into the alleys leading to the sea. The movement outward is carefully staged: the coded passage through inner defenses gives way to an escort across the moat, and then to a final approach through the city.

The Wharf and the Crew

Outside the cordon around the Erasmus wharf, the accompanying samurai stop and signal the ten men forward before withdrawing into the darkness. Naga’s party passes through the barriers and is admitted to the jetty without comment, despite the greater number of flares and guards there. Yabu now takes charge of the arrangements. When he asks whether everything is ready, the senior samurai confirms that it is; Yabu then checks that Blackthorne understands the plan and tells him to hurry.

Blackthorne sees his samurai assembled in a loose square and sends Uraga across to them, as previously arranged. He boards the Erasmus and checks the ship as he moves, then reaches the quarterdeck. The darkness has not yet yielded to dawn, but the signs point to calm seas and fair weather. At the wharf, Yabu and Naga confer while Uraga explains the situation to his vassals. The barriers open again, and Baccus van Nekk and the rest of the crew stumble into the clearing, apprehensive and surrounded by guards. Their sudden appearance confirms that the secret movement is not merely a transfer of the ship: Blackthorne is also being reunited with the men needed to work her.

Blackthorne Takes Command

The crew’s first response is confusion. Baccus van Nekk and Vinck ask what is happening; the men have been woken and brought to the wharf with little explanation. Blackthorne quiets them and tells them they are taking the Erasmus to a safe harbor across the bay. When Vinck objects that they do not have enough men, Blackthorne answers by assigning the work around a tow. Ginsel is to sound ahead, Vinck is given the helm, Jan Roper and Baccus van Nekk are stationed at the forewinch, Salamon and Croocq are sent aft, and Sonk is ordered below to check the stores and find grog if possible.

The distribution of tasks makes the plan concrete: the Erasmus will not make the passage under her own power alone, and her crew must be ready to sound the water, steer, handle the winches, and inspect supplies. Blackthorne’s authority is expressed through practical decisions rather than a speech. He takes account of the ship, her people, the route, and the weather; the crew’s anxiety remains, but it is converted into work. At the same time, the operation joins two kinds of command. Yabu has secured the route and arranged the departure; Blackthorne directs the ship and crew once they are aboard.

Toward Safer Water

Before casting off, Blackthorne inspects the arrangements and checks the wind with the habits of a pilot. Even in the broad, apparently benign waters of Yedo harbor, he knows a sudden squall could make the passage dangerous. Once the bow hawsers are secured to the other craft, he gives the order to cast off. The towing captain signals and lets his galley ease away from the jetty. Naga is aboard that vessel with samurai and the rest of Blackthorne’s vassals; Yabu remains beside Blackthorne on the Erasmus’s quarterdeck.

The Erasmus heels slightly under the pull and trembles as the current takes hold. Blackthorne and his crew are jubilant to be at sea again, although their excitement does not erase their anxiety. Ginsel leans over the small roped platform on the starboard side, swings the lead, and calls out the fathoms. The crew answers Blackthorne’s warning to slow down, and the two ships proceed together into the harbor stream with riding lights at their mastheads. The transfer thus ends in motion rather than in secure arrival: the vessel has left the jetty, but the passage still requires careful navigation.

Navigation as Leverage

The operation draws on the same seamanship that governs Blackthorne’s wider experience in the story. He has learned that charts can be too vague to guide a voyage reliably and that longitude cannot be fixed by the methods available to him. A rutter—the accumulated observations of pilots who have sailed a route—can record courses, depths, currents, winds, storms, anchorages, and hazards, but its usefulness depends on the accuracy of its pilot and copies. The transfer’s attention to soundings, wind, current, towing, and weather gives practical form to that knowledge: safety at sea is made from observation and judgment, not from the destination’s name alone.

Earlier, Rodrigues chose an open-water course from the Izu coast toward Cape Shinto because hugging the shore would cost too much time. Blackthorne also recognizes the European practice of moving a ship away from a threatened shore and preparing its guns when danger approaches. These earlier lessons frame the wharf departure without turning it into a naval engagement: here, the escort, barriers, cipher, and tow replace cannon fire. The scene’s decisive change is that the Erasmus is no longer simply a ship held at a guarded berth. With Blackthorne aboard, his crew at their stations, and the tow underway, she becomes a vessel in passage toward safer water.
