in his campaign against the royalists. In the same place stood out a bridge of three letters "VVM" (Long live the Virgin Mary). Resting on the bridge, and passing over it, was a crowned eagle. His position showed half profile. Already advanced the War of Independence the insurgents used another flag. The banner with the Virgin had a strong religious connotation and therefore it was considered appropriate to replace it. Being before that of Iguala, it also used three colours: white, blue and red. The new flag was displayed on merchant ships that ran along the Gulf coast between Mexico and the United States. Its acceptance was immediate, to the point that in North America it was greeted with 21-gun salutes.
