Katherine Horn

When the two little daughters of a young widower are told that he is preparing to bring up to the house to see them, a young lady who is to be their new mamma, they are at once plunged into the depths of despair. They feel that their home will be no longer bearable if they are to have a stepmother, so they run away to go out in the world to earn their own living.

English officer Bertie Cecil falls into severe financial distress and is falsely accused of a forged note. To protect the honor of a lady and cover for his younger brother (the real culprit), Bertie remains silent and accepts the appearance of guilt. Facing ruin and arrest, Bertie flees England and joins the French Foreign Legion (or Chasseurs d'Afrique) in Algeria under an assumed name. His English girlfriend travels to Africa to find him. Meanwhile, Cigarette, the fierce "child of the regiment" and camp follower develop deep feelings for Bertie. Following dangerous military conflicts and acts of self-sacrifice in the desert, Bertie's name is eventually cleared, allowing him to return to England.
