Antero Rubin 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.
Rubin's father, a career officer who served with distinction under General Prim in the 1860 war against Morocco, steered Rubin toward a military career. Rubin enrolled in the Spanish Army May 11, 1868, and in 1869, at the age of 16, volunteered for service in Cuba. Rubin returned home shortly afterwards with his statutory promotion to lieutenant and began his studies at Vigo and Santiago de Compostella.
In 1869 Rubin, a captain, embarked once more for Cuba. He prosecuted several campaigns against the Cuban insurgency, marked by successes at Estella and Somorrostro.
On February 4, 1898 Rubin was promoted to Brigadier General of the Regimento de Maria 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.
Rubin was one of the few Spanish commanders not discredited by the war. He reached the rank of Lieutenant General in 1908 and became Captain General of Galicia in 1917.
