Night of the Long Knives - S1.E14

Tony is shot by Afghani tribesmen and left for dead, and they then take Doug prisoner. Doug is taken before Singh, the head of the Afghanis fighting against the British in 1876, while Rudyard Kipling rescues Tony and takes him to the English fort. The Afghanis are preparing for a massive attack on the English, the 'Night of the Long Knives'. With the aid of a blind slave, Doug escapes and gets back to the fort, while Kipling is captured. The general in charge has been ordered to only defend himself, so he has the head of the Afghani forces under English command launch an ""unofficial"" attack. Doug and Tony accompany them and rescue Kipling, and Singh is killed in the attack.
