The Battle of Puebla, also known as the Battle of May 5 took place on 5 May, Cinco de Mayo, 1862, near Puebla de los Ángeles, during the second French intervention in Mexico. French troops under the command of Charles de Lorencez repeatedly failed to storm the forts of Loreto and Guadalupe situated on top of the hills overlooking the city of Puebla, and eventually retreated to Orizaba in order to await reinforcements. Lorencez was dismissed from his command, and French troops under Élie Frédéric Forey would eventually take the city, but the Mexican victory at Puebla against a better equipped force provided patriotic inspiration to the Mexicans.
The second French intervention in Mexico, also known as the Second Franco-Mexican War (1861–1867), was a military invasion of the Republic of Mexico by the French Empire of Napoleon III, purportedly to force the collection of Mexican debts in conjunction with Great Britain and Spain. Mexican conservatives supported the invasion, since they had been defeated by the liberal government of Benito Juárez in a three-year civil war. Defeated on the battlefield, conservatives sought the aid of France to effect regime change and establish a monarchy in Mexico, a plan that meshed with Napoleon III's plans to re-establish the presence of the French Empire in the Americas. Although the French invasion displaced Juárez's Republican government from the Mexican capital and the monarchy of Archduke Maximilian was established, the Second Mexican Empire collapsed within a few years. Material aid from the United States, whose four-year civil war ended in 1865, invigorated the Republican fight against the regime of Maximilian, and the 1866 decision of Napoleon III to withdraw military support for Maximilian's regime accelerated the monarchy's collapse. Maximilian and two Mexican generals were executed by firing squad on 19 June 1867, ending this period of Mexican history.

The 1st Regiment California Cavalry was a cavalry regiment in the Union Army during the American Civil War. It was first formed as the 1st Battalion, 1st Regiment California Cavalry between August and October 31, 1861, at Camp Merchant near Oakland.

In 1863 seven more companies were raised to bring the regiment to a full strength of twelve companies. The five companies first organized were mustered out August 31, 1864, as the terms of service of most of the men had expired.
