On August 2, 1867, a small group of U.S. soldiers found themselves outnumbered and surrounded in the Wyoming Territory. Armed with new rifles and shielded only by wagon-box walls, they faced hundreds of Lakota, Cheyenne, and Arapaho warriors. In this episode, we explore the Wagon Box Fight and the lasting impact of one of the most pivotal but often forgotten battles of Red Cloud's War.

In 1532, the tiny town of Guns is all that stood between the Ottoman Empire and Vienna. A young knight, Nikola Jurisic, inspired fewer than 1,000 villagers to stand up against the brutal daily assaults of nearly 100,000 Turks. The heroism of those defenders helped halt the Muslim takeover of Europe, and that's why the battle of Guns is a battle you might not know, but should.

Rome spent centuries flexing its muscle as one of the greatest military forces the world has ever known, but on May 6, 1527 Rome failed to keep out a bloodthirsty army that spent the subsequent months murdering Romans and stripping the city of its wealth. Many of the invaders had a bigger target than mere looting: The Catholic Pope Clement VII.

Their sacrifice during this Sack of Rome bought the precious minutes Clement VII needed to escape capture. His survival contributed to, in parts, motivating King Henry VIII from breaking from the Catholic Church, as well as promoting the Lutherans into their irrevocable break with the Church.
