Portuguese Auxiliary Division in Spain, 1835-37
When Don Carlos arrived back in Spain in 1835 the Portuguese Liberals felt obligated to fulfil the obligations of the Quadruple Alliance, and return the favour to the Spanish Liberals for their help during the recent Liberal War in Portugal (Vieira, 2004). As a result a Portuguese Auxiliary Corps was sent to Spain to fight the Carlists (Viriatus Miniatures: Divisão Auxiliar a Espanha). This three brigade force contained 6,000 foot and 750 horse when it entered Spain in Nov 1835 (Cairns, 1994b; Viriatus Miniatures: Divisão Auxiliar a Espanha; Duncan, 1997, says they had 8,000 men). The force was recruited from the best regular units, although one unit, the “Caçadores do Porto”, was said to have been made up of adventurers of all nations left over from Portugal’s recent civil war. Included at least one regiment of well-equipped lancers. The first Portuguese forces to enter Spain had the title of Vanguard of the Auxiliary Corp, although they became the 3rd Brigade when the rest of the expedition arrived.
Note Viriatus Miniatures: Divisão Auxiliar a Espanha refers to this force as both “Corpo do Exército Auxiliar a Espanha” and “Divisão Auxiliar a Espanha“, i.e. as both an Army Corps and a Division. Although larger than a division, that is the title most other sources use. .

The Brigada Auxiliar Portuguesa fought for the Spanish government in Catalonia (Nuno Pereira, private communication). It was nothing to do with the Portuguese Auxiliary Division. It contained:
Grenadiers of Oporto (Granaderos de Oporto). Made up of English, Portuguese and Spanish volunteers. recruited during the Portuguese Civil War. It was commanded by the English brigadier Dodgin until his death at the Battle of Grá (12 Jun 1837).
Portuguese Carlists
After losing the Liberal Wars the exiled Portuguese Absolutists wanted to continue the fight for what they believed in and supported by their leader, Don Miguel, joined Don Carlos forces (Vieira, 2004). This way, many Portuguese came from Portugal (where Absolutist guerrillas were still active), England, France and Italy to join the Carlist ranks. The Portuguese in the Carlist Army even formed a Company commanded by the captain António Teles Jordão. Besides many soldiers there were also several Portuguese officers loyal to D. Miguel in the Carlist Army.
