The British commissioner Colonel Wylde attended as an observer, because of Britain's recent role as mediator in the conflict and the 1835 Lord Eliot Convention on prisoners of war, mainly to end the indiscriminate executions by firing squad that had been committed by both sides.
The first article of the treaty was related to Basque home rule (fueros) and declared, "Captain General Don Baldomero Espartero will strongly recommend to the government the compliance of his offer to commit formally to a proposal to the Spanish Parliament authorizing or modifying the fueros".
[1] Although the treaty had been signed by high-ranking officers, the Navarrese battalions, above all, felt a certain repugnance, distrust and discontent, and some officials still intended military revolt.
Afterwards, Rafael Maroto gave a stirring speech: "Volunteers and Basque peoples, no one was more devoted than I to restoring the right to the Spanish throne to Carlos María Isidro de Borbón, but none is more convinced by the experience of a multitude of events, that never could this prince bring my country happiness, which is the sole motive of my heart".
[2]With the conflict at an end, Maroto resumed the rank of lieutenant general and was named Minister of the Supreme Tribunal of War and Marine.
