execute the ringleaders, but they refuse. Before Markoff can react, the fort is attacked by Tuaregs, forcing him to rearm his men. The initial assault is beaten off, but each new attack takes its toll. Markoff props up the corpses at their posts to deceive the enemy. The final assault is repulsed, but Beau is shot, leaving Markoff and John the only men left standing. Markoff sends John to get bread and wine. He then searches Beau and finds a small pouch and two letters. When John sees what Markoff has done, he draws his bayonet, giving Markoff the excuse to shoot the only witness to his theft. However, Beau is not yet dead and manages to spoil Markoff's aim, allowing John to stab him. John and Beau hear a bugle announcing the arrival of reinforcements, Digby among them. Beau dies in his brother's arms after telling him to take one of the letters to Lady Brandon and leave the other, a confession of the robbery, in Markoff's hand. John escapes unseen. Digby volunteers to find out why there is no response from the fort. He discovers Beau's body and, remembering his childhood wish, gives him a Viking funeral. He places Beau on a cot, with a "dog" (Markoff) at his feet, and sets fire to the barracks. Then he too deserts. He finds John outside the fort. Later, they encounter two American Legionnaire friends and begin the long journey home. Desperate for water, they find an oasis, but it is occupied by Arabs. Digby tricks them into fleeing by sounding a bugle to signal a charge by non-existent Legionnaires, but is killed by a parting shot. John returns home, and reunites with Isobel. Lady Brandon reads aloud Beau's letter, which reveals that as a child he was hiding in a suit of armor and witnessed her selling the "Blue Water". Realizing years later she had replaced it with a fake, he had stolen the faux gem to protect her from being found out - his ‘’beau geste’’.
