"Felix Maria Calleja del Rey was born on November 1, 1753 in Medina del Campo, Valladolid, Spain. He led a rather ordinary childhood, typical of his social standing and, not surprisingly, decided on a military career early in life. His exceptional intelligence was noted from the start and he began to specialize in military cartography. Unfortunately, his early career was not marked with much success. In 1775 he participated in a failed expedition against Algiers. In 1782 he was on hand for the successful capture of Menorca Mahon harbor but the same year was among the Spanish forces thwarted in the siege of Gibraltar. After serving a few years as head of a military academy, the fortunes of Captain Calleja del Rey would begin to change with his transfer to the New World. In 1789 the Count of Revillagigedo went to Mexico City to take up the post of Viceroy of New Spain and Calleja del Rey was among his party. Colonial service allowed for more rapid promotion and soon he was commanding an infantry brigade in San Luis Potosi and under the orders of Viceroy Miguel Jose de Azanza he successfully suppressed insurgent Indian forces in the area. This was a time when rebellion was becoming a major problem across New Spain and when elements in the United States were eager to take advantage of the misfortune of Spain to try to grab Texas.
When American filibusters (land pirates) allied with Mexican revolutionaries invaded Texas, Calleja del Rey was among those Spanish officers who led royalist troops to victory against them. Many of the officers under his command would go on to great fame in Mexico with some, like Ignacio Allende, fighting for the revolution against the monarchy and others, like Antonio Lopez de Santa Anna, fighting for both. In 1811 and 1813 he successfully suppressed rebellions against royal authority and even found the time to marry a local girl, Francisca de la Gandara, daughter of the owner of the hacienda de Bledos. These years gave him valuable experience in putting down revolution, impressing upon him the importance of well cared for and disciplined troops as well as making an example of rebels. In time, he would be key in eliminating the three most famous Mexican revolutionaries against Spain and establish a reputation as one of the most brilliant and successful commanders to ever see action on the battlefields of Mexico. The most famous insurgent leader of all (and the man still hailed as the "Father of Independence" in Mexico today -which is odd given that he was defeated long before independence was actually achieved) was the heretical priest Father Miguel Hidalgo who incited a major rebellion with his famous Grito de Dolores on September 16, 1810.
This was a combination of political rebellion and race war with Padre Hidalgo inciting the most heavily mixed race elements to rise up and kill those of Spanish blood. Huge mobs took to the streets and across New Spain city after city fell into rebel hands. Mexico City fell into a panic as Padre Hidalgo defeated the royalist army and marched toward the capital with 80,000 men. However, at the critical moment, the Padre lost his nerve and ordered a retreat. Calleja del Rey was, at the time, a brigadier general in command of a cavalry division at San Luis Potosi and Viceroy Francisco Javier Venegas summoned him to come to the aid of Mexico City. It was the start of a masterful campaign. Calleja del Rey and his royalist forces first met the rebels on November 7, 1810 on the plains of San Jeronimo Aculco and completely wiped them out. On November 25 his royalist forces re-captured Guanajuato and on January 21, 1811 liberated Guadalajara. The rebels retreated, despite their still swelling ranks, and Calleja del Rey gave chase. On January 17, 1811 at the battle of Calderon bridge, his tiny force of 6,000 royalists attacked and routed an army of 100,000 rebels in a stunning victory that ensured the revolution would be crushed and put off the independence of Mexico for another ten years
