Kapitän zur See Ernst Lindemann looked back at the squadron’s sojourn at Batavia as one of the highlights of their entire journey thus far. The concern of potentially offending French sensibilities or the occasional manifestation of British hauteur was absent here among their Dutch cousins. The parade of dignitaries that had come aboard the Seydlitz and the other ships of the Fourth Cruiser Squadron had been open, friendly and disingenuous. The visits ashore, whether the formal calls in company with Admiral Lütjens, or the unofficial visits to the restaurants and coffeehouses of Batavia, were truly relaxing; Lindemann had even taken the opportunity to acquire some antique porcelain as a gift for Frau Lindemann. All in all he would miss Batavia.
“Signal from the flagship Herr Kapitän,” said the officer of the watch, awakening Lindemann from his private reverie. “Prepare to weigh anchor.”
“Make it so,” replied Lindemann laconically. He walked across the bridge and checked the course plotted for them. He felt reassured by the presence of the latest chart of the Sunda Strait provided by their hosts. Lindemann was concerned that the squadron might risk grounding on the sandbanks and shoals that made the Sunda Strait dangerous to large ships, but, he felt, with the latest information they should avoid mishap. Lütjens had also planned the time of their departure well; at an easy ten knots the squadron would transit the strait in daylight, and once clear they would have open ocean before them for thousands of miles.
“Signal from the flagship,” reported the officer of the watch. “Weigh anchor!”

Fregattenkapitän Heinrich Drau of the tanker Altmark stood on her bridge, eyes on the Derfflinger, alert for any warning that the charts they had were in error. Thankfully there was little merchant traffic today; the big battlecruisers and Altmark, deep in the water with a full fuel load, were able to maneuver without worry of potential collision. Those small Javanese bankas that neared them sheered away quickly.
Hartmann, the ship’s navigator, checked his charts and called out, “Herr Kapitän, we are nearing the final marker…”
Ahead Drau could see that the Derfflinger had shifted course to starboard; Seydlitz now began to follow her. Drau held on a moment… “Starboard twenty!” he commanded. Altmark’s helmsman swung his wheel and deep below the rudder bit, swinging the tanker onto its new course.
Drau looked at the waters ahead, and thought that they looked a deeper blue. It was perhaps his imagination, but in any case the Sunda Strait was behind them.
“Signal from the flagship Herr Kapitän. Set speed fifteen knots.”

The Fourth Cruiser Squadron had enjoyed pleasant weather on its voyage across the Indian Ocean. Save for the passing merchantman – most of which were Dutch or German – it had been uneventful. In the circumstances Admiral Lütjens had thought it reasonable to maintain an air search during the daylight hours – this would be the last opportunity for the ships to exercise their air observation units, for here in the open ocean there was much less concern for potential violations of sovereign air space.
“Good afternoon Herr Admiral,” said Langsdorff as Lütjens stepped on to the bridge of Derfflinger.
“Good day Langsdorff,” replied the admiral. “What is our position?”
Langsdorff indicated on the plot. The German battlecruisers were nearing the half-way point on their voyage to the Red Sea; the Bharati-held Maldives were to their north, the Chagos Archipelago to their south.
“Good,” Lütjens concluded.
The wireless officer entered the bridge in haste. “Herr Kapitän,” he reported. “Scout Two has sighted a flotilla of at least four ships. Composition uncertain.”
“Give me the report,” Langsdorff replied, and took the paper flimsy. He quickly marked the coordinates of the ships the scout reported. “Eighty miles north of us, sailing south south-west at twelve knots.”
Lütjens gave half-a-frown. “On that bearing it is likely a squadron of the Bharati Navy. No doubt to keep watch on us.”
“No doubt Herr Admiral,” Langsdorff agreed.
“Order the scout to maintain contact; signal the Seydlitz to launch a relief aircraft. Maintain a strict watch on Seetakt. Fleet Command has not given us any reason to be concerned with potential Bharati reaction to our presence but there is no reason to be complacent.”
