As a 1st lieutenant, Danjou was part of the French army that fought in the Crimean War, and served during the Siege of Sevastopol.

On 29 April, Colonel Jeanningros was informed that an important convoy was on its way to Puebla with three million francs and material and munitions for the siege.

Danjou had the company take up a square formation and, even though retreating, he drove back several cavalry charges, inflicting the first heavy losses on the enemy.

Looking for a more defensible position, Danjou decided to make a stand at the nearby Hacienda Camarón, an inn protected by a 10-foot (3.0-meter) high wall.

Out of admiration for their courage, he spared the surviving men and allowed them to form an honour guard for the body of Captaine Danjou.

A commemorative marble plaque is affixed to the facade of the birthplace of Captain Danjou, in Chalabre (Aude, France).

Ramirez was soon arrested and the hand retrieved by Lieutenant Karl Grübert of the Austrian army, which replaced the Foreign Legion in this conflict on 17 July 1865.
