Based on the terms of the accord, Henry sent 6000 English troops to fight (at the expense of Brittany) under the command of Lord Daubeney.
[1][2] According to Currin, the treaty redefined Anglo-Breton relations, Henry started a new policy to recover Guyenne and other lost Plantagenet claims in France.
[4] In an attempt to avoid annexation, in 1486, Duke Francis arranged for his daughter to be married to Maximilian, heir of the Holy Roman Emperor.
A fame of war he liked well but not an achievement; for one he thought would make him richer, and the other poorer; and he was possessed with many secret fears touching his own people, which he was therefore loth to arm, and put weapons into their hands.
Yet notwithstanding (as a prudent and courageous prince) he was not so averse from a war but that he resolved to choose it rather than to have Brittaine carried by France; being so great and opulent a duchy and situate so opportunely to annoy England either for coast or trade.Henry VII's response to the imminent annexation of Brittany into France was to sign the Treaty of Redon in February 1489, promising 6000 troops as long as the Bretons financed their deployment.
[4] Furthermore, Henry VII was anxious to emphasise that the presence of English troops in Brittany was not for the purpose of conquest; in January 1489, the papal ambassador in England wrote in a dispatch to Pope Innocent VIII that Henry "is compelled at present to defend Breton interests, both on account of the immense benefits conferred on him by the late Duke in the time of his misfortunes, and likewise for the defence of his own kingdom".
This culminated in the Treaty of Etaples in 1492, under which the French would pay the equivalent of £5000 a year to Henry - 5% of his annual income - in return for English withdrawal.
