It is a common occurrence in history that, after a victory, flags captured from the enemy are used as trophies. During the American Revolutionary War, Bernardo de Gálvez, governor of Louisiana, was victorious over the British in Florida, not only in Pensacola, but also in Mobile and at the forts along the Mississippi River. On this occasion, King Charles III ordered the captured flags to be sent not only to the parish in New Orleans, but also to various Spanish religious centers to be proudly displayed. The cathedrals of Santiago de Compostela and Seville, the Church of Our Lady of Atocha in Madrid, and the Basilica of Our Lady of the Pillar in Zaragoza were the chosen locations.

After conducting the necessary inquiries, it has been confirmed that no flags remain in these institutions today. However, Bernardo de Gálvez kept a Union Jack and other captured British regimental flags as souvenirs. In 1903, the heirs of the Gálvez family donated them to the Artillery Museum and today they are exhibited in the Army Museum of Toledo.
