Antero Rubín Homent (February 15, 1851 - May 1, 1935) was a Spanish general and politician noted for his long service in Cuba. He fought in the Spanish American War, served in the Cortes Generales, and spent the final years of his life as Senator for the province of Zamora.
Rubín's father, a career officer who served with distinction under General Prim in the 1860 war against Morocco, steered Rubín toward a military career. Rubín enrolled in the Spanish Army May 11, 1868, and in 1869, at the age of 16, volunteered for service in Cuba. Rubín returned home shortly afterwards with his statutory promotion to lieutenant and began his studies at Vigo and Santiago de Compostella.
On February 4, 1898 Rubín was promoted to Brigadier General of the Regimento de María Cristina. He conducted himself well at the Battle of Las Guasimas, where his small force fought a very successful rearguard operation, bloodying Joseph Wheeler's V Corps before retiring in good order to Santiago de Cuba. This city was put under siege after a bloody struggle at San Juan Hill and on July 18 General Jose Toral reached an agreement with the Americans and capitulated.
