Buuxi weedha soo socota: Kadib heshiiskii Fontainebleau ee ay wada galeen Faransiiska iyo Spain bishii Oktoobar 1807, kaas oo lagu heshiiyay duulaankii iyo kala qeybinta dhulka Portugal ee saddexda boqortooyo, ciidamada Faransiiska ee uu hoggaaminayay Janaraal Junot ayaa galay Portugal, kuwaas oo ka codsaday taageerada Ingiriiska. Sidaa darteed, bishii Luulyo 1808 ciidamo uu hoggaaminayay Duke of Wellington, oo waqtigaas loo yaqaanay Arthur Wellesley, ayaa waxay galeen Portugal waxayna ka adkaadeen ciidamada Faransiiska dagaalkii Battle of
Roliça iyo Vimeiro. Tani waxay ku qasabtay Junot inuu ka wada xaajoodo Heshiiskii Cintra, kaas oo horseeday daadgureynta ciidanka Faransiiska ee Portugal. Bishii Maarso 1809, Marshal Soult wuxuu hoggaamiyay ciidan cusub oo Faransiis ah oo u sii gudbay koonfurta magaalada Porto ka hor inta aysan dib u celin ciidamada Portugal iyo Ingiriiska oo lagu qasbay inay ka baxaan.
