Papers on HMS Unicorn and related Admiralty records provide the basis for the proposed implementation. These documents help reconstruct how the network might develop in 1939 and 1940, but they do not support a confident narrative for 1941 and beyond. An earlier loss or weaker cruise by Admiral Graf Spee, or the detection of Deutschland near Newfoundland, could produce political and morale effects out of proportion to the merchant ships directly saved. Hitler's sensitivity to capital-ship losses might then affect Bismarck or Tirpitz, though that remains a downstream question rather than a prediction. Primary sources can establish a counterfactual's starting conditions while cumulative consequences become progressively less certain.

Archive evidence sets limits on the tender counterfactual
Admiralty papers support the network's early implementation, while later effects on German raiders and capital ships remain deliberately uncertain.
