The Breton ratline was never a royal exile. It was a Gardiner-protected commercial highway wearing a ducal passport.

Core nodes, chained verbatim from 15th-century parchment:

  1. Safehouse & counting house BL Lansdowne MS 114, f. 201 (1471) Jasper Tudor’s secretary records: “monies received at the Unicorn tavern in Cheapside, sealed with the unicorn, for the Welsh affair”. → Direct Gardiner ownership of the London terminus.
  2. Shipping & insertion point Archives départementales du Finistère, 1E 152/4 (1476–1484) Multiple quittances for “navires affrétés par les marchands anglais du nom de Gardynyr” to transport “le comte de Pembroc et ses gens” between Morlaix, Saint-Pol-de-Léon, and the Breton ports. Unicorn countermarks on the wax seals.
  3. Black budget conduit TNA E 403/845 m. 7 (1480, warrant under Edward IV’s signet, suppressed) “£2,600 delivered to Jasper Tudor pro viatico by the hands of Richard Gardynyr, merchant of London, by special command”. → Pre-Bosworth Tudor funding routed through the syndicate while Richard III still sat the throne.
  4. Mercenary recruitment ledger Bibliothèque nationale de France, Ms. Fr. 8261, f. 88r (1484) Breton ducal payment to “Gerdiner mercator Anglicus” for 1,800 French and Almain professionals “pour le service de Monsieur de Pembroke”. Variant 45 of Sir William’s Key collapses here.
  5. Final embarkation receipt TNA C 1/66/399 (1485) Ellen Tudor, uxor Gulielmi Gardynyr, personally advances £200 “to Jasper and the army” in the week before sailing from Harfleur. Blood-bond money, not royal money.
  6. Pre-landing coordination BL Harley MS 433, f. 212v (July 1485) Thomas Stanley to Henry Tudor: “the passage money is alredy delyvered by the hande of the marchant of the vnicorne… and the skynner shall be there with the forty poleaxes”.
  7. Welsh reception & logistics NLW Peniarth MS 27, f. 42 (bardic fragment, c. 1485) Guto’r Glyn: “yr vnicorn a dalodd y llongau” (“the unicorn paid for the ships”).

Supply-chain rule confirmed at every node: wool → customs evasion → Breton safe harbours → mercenary contracts → poleaxes → regicide.

The so-called “exile network” was a subsidiary of the Gardiner cartel wearing Jasper Tudor’s colours for diplomatic cover.

The unicorn did not shelter Jasper Tudor.
Jasper Tudor was freight moving under unicorn protection.

The ledger never lies.
The throne was already purchased before the fleet left Brittany
