After Robert-Houdin retired, he devoted himself to his inventions with electricity and his writings. His home le Prieuré (the Priory), was a marvel in advancement.[3] His home was run entirely by electricity.
In 1856, he was asked by Louis-Napoleon to pacify the tribes in French Algeria. During this period, the French Army commanders maintained order in the newly pacified region. They supervised local Muslim administrations and the bureaux arabes. These areas were closed off to colonization by the Europeans.
Napoleon III was worried about a religious tribe called the Marabouts. The Marabouts were able to control their tribe with their faux magical abilities.[5] They advised their leaders to break ranks with the French.[2] Napoleon wanted Robert-Houdin to show that French magic was stronger.[5]
The magical mission began with an informal show at the Bab Azoun Theatre in Algeria where he would give performances twice weekly.[2] He also gave many special galas before the country’s tribal chiefs. He used The Light and Heavy Chest during these performances, but instead of playing it for comedy as he had in Paris, here he played it straight. Robert-Houdin once invited the strongest tribesman on stage and asked the Arabian to pick up the wooden chest placed on stage. The Arabian picked it up with no problem. Then Robert-Houdin announced that he was going to sap his strength. He waved his wand and declared, "Contempler! Maintenant vous êtes plus faible qu'une femme; essayer de soulever la boîte." ("Behold! Now you are weaker than a woman; try to lift the box.") The Arabian laughed at this and with all of his might, pulled on the handle of the chest. But it would not budge! He tried and tried until he tried to rip it apart. Instead, he screamed in pain, as Robert-Houdin had rigged the box to give the Arabian an electrical shock if he tried to rip the handles off. The Arabian let go of the handle, ran off into the aisle, and ran screaming out of the theatre.[3] A variation of this event was included in the movie The Illusionist.
After his performances were done, he gave a special presentation for several chief men of their tribe. He was invited to the home of the head of the tribe of the desert interior, Bou-Allem. In dawn of the Arab desert, Robert-Houdin was challenged to do a special trick. He obliged by inviting one of the rebels to shoot at him with a marked bullet, which he caught between his teeth. He was given a certificate from Bou-Allem,[4] who wore a red robe symbolizing his loyalty to France. With this scroll praising his mysterious manifestations, Robert-Houdin went back to France with the mission accomplished.[2]
"The blow was struck," Robert-Houdin said, "...henceforth the interpreters and all those who had dealings with the Arabs received orders to make them understand that my pretended miracles were only the result of skill, inspired and guided by an art called prestidigitation, in no way connected with sorcery." He went on to say, “The Arabs doubtless yielded to these arguments, for henceforth I was on the most friendly terms with them."[4] He was rewarded for his services of the French government by suppressing any possible rebellion.[5]
