June 25, 1876 — Custer is defeated and killed at Little Big Horn

General George Armstrong Custer went into battle at Little Big Horn under a number of false impressions.

He was under the impression that he would be facing no more than 800 Native Americans, rather than more than twice that number – Sitting Bull and Crazy Horse had recruited assiduously, knowing that a battle was coming. He was under the impression that his major challenge would be preventing the escape of the enemy forces, rather than defeating them. And finally, he was under the impression, based on these assumptions, that the force under the command of his subordinate Major Reno would be far more effective in battle than it proved.

But with Reno’s forces isolated and routed, Custer’s forces were outnumbered and surrendered. More than 200 men in Custer’s army, including Custer himself, were killed.

January 8, 1815 — The Battle of New Orleans takes place

In the annals of military pointlessness, few battles are quite as ridiculous as the Battle of New Orleans. It was fought 16 days after the official end of the War of 1812, of which it was a part, due to the fact that the peace treaty was signed in Europe, and the news took two months to reach America.

The Battle of New Orleans was important to later American history, though. It ended the war with a decisive American victory (in a war where neither side had managed to seize the advantage over the other), and it brought to prominence a commander named Andrew Jackson, who would later become the seventh President of the USA.
