So soon as he was in a con- dition to answer questions he gave the following probable, and indeed true explanation of the catastrophe. Being moved to the depths of his soul by the sight of the French flag, and becoming conscious at last of the crime of treason to his country that he was about to commit, Roch rushed through the passage. Having reached the cavern he made for the magazine, where considerable quantities of his ex- plosive was stored, and before Ker Karraje, Serko and the others could prevent him he had caused the explosion of Backcup.
