As a portuguese I'm honoured for that Angiolillo. I hope that this two excerpts of the 1st edition
The Aircraft of the Cross of Christ( Os Aviões da Cruz de Cristo) by Mario Canongia Lopes and Jose Manuel Rodrigues Costa may help you.
"....13 Portuguese pilots chose to go on fighting, the most famous of them
being Captain Oscar Monteiro Torres, who had initially served with 10th Sqd.
RFC. Monteiro Torres had establish a friendship with the famous French Ace
Georges Guynemer, who quite admired him and who would invite him to join his
famous Escadrille de Cigognes - SPA 3. Since Guynemer died in combat
shortly after having made the invitation, Monteiro Torres never joined the
Storks and went to another famous fighter squadron - SPA 65, based at
Soissons, equipped with SPASD S.7C1.
On 20 Nov. 1917 he fought an heroic and unequal aerial combat, having downed an Halberstadt and facing several Fokkers afterwards, between Chemin des Dames and Laon, being brought down after a glorious fight, and in dramatic circumstances, not without having yet brought down another enemy...Monteiro Torres is knocked down by the Ace
Rudolf Windisch (22 victories, being Torres his 6th ) of the Jasta 32b. Seriously injured, Monteiro Torres manages to land, coming to die the next day in a German hospital.
Like trophy of victory Rudolf Windisch demands the spad VII (cn S 4268) of Monteiro Torres (I think what would be a relatively common practice, not in order to fly thr aeroplane like a weapon of war, but using it like object of demoralizing propaganda ...), it repaired the aeroplane, substituting the wheels for others of an Albatros D.V, told it to paint of red (inferior surface in blue) and to substitute the french cocades for the German crosses, but leaving the lists, the dragon and the SPA 65 original insignia
....
of note is the fact that some pilots painted on their machines the
Portuguese colours, either by modifying the French cocardes (just a matter
of painting the inner blue and white circle in green, since the outer ring
was red), or by adding diagonal red and green stripes over the rear
fuselage, such as used by Santos Leite, Sousa Maya and Lelo Portela on their
SPAD S.13 C1, along with the Jeanne d'Arc insignia of Escadrille SPA 124,
that replaced Lafayette Escadrille, to which these pilots belonged."
