A plan for an Atlantic raid had to answer several different questions. What was worth attacking? How would it be found? What would make an attack possible? And how could the ships remain useful afterwards? The orders and the later German command report allow us to separate those questions before following the voyage itself.
Finding a target
The general orders made merchant shipping the objective, especially traffic towards Britain. They acknowledged that intelligence about convoy departures and routes could not ensure an interception across an enormous ocean. Independently sailing ships were targets as well. B02
This was an operation whose success depended on opportunities. Reaching the trade routes did not itself put a convoy within gun range.
Two ships, different jobs
Against a convoy with a battleship escort, Bismarck was to occupy the defender while Prinz Eugen approached from the other side. Bismarck was to avoid becoming fully engaged. The cruiser’s opportunity depended on the escort being drawn sufficiently far away; an escort staying close to its merchantmen could defeat the scheme. B02
Discovering the escort’s strength was another difficulty. Shipboard aircraft might help, but weather and the tactical situation could prevent their use. If Prinz Eugen encountered defending cruisers, the orders required her to break off and report. The proposed partnership therefore came with explicit limits. B02
Why proceed?
In his report to Hitler on 6 June, Admiral Erich Raeder explained why the operation had not waited for additional battleships. He described uncertainty over Tirpitz’s readiness and Scharnhorst’s return to service, and argued that further delay was strategically undesirable. B19
That explanation was written after Bismarck had been lost. It records how the naval leadership defended its decision; it cannot settle whether a different decision would have succeeded.
Beyond the horizon
Raeder’s account describes an intended unobserved passage through the Great Belt, Skagerrak and Norwegian Sea. Discovery did not automatically cancel the mission: the fleet commander retained discretion to shorten or abandon it. The report also records tankers and supply ships positioned to support the operation, alongside severe limits on long-range air reconnaissance during the outward passage. B19
The two warships thus belonged to a larger operation. Their ability to keep moving depended on support that readers will seldom see in photographs of the battleship.
Reading a plan before the battle
These documents reach us through modern reproductions and translations; their archival originals remain to be checked. The general orders describe intended conduct, while Raeder’s report supplies a retrospective command explanation. Neither should be read as a complete account of what happened at sea.
For the next stage of the story, keep the sequence of problems in mind: escape observation, reach the shipping routes, find a vulnerable target, and preserve the strength to attack it. Each stage could change the choices available at the next.
