I found text which would well support your composition, but all is in French, from a book, and I have to translate the etxt by retyping it for translation in Englsih or German.
Actually in short, the battle of Alger between the French army and Abd-el-Khader occurred on 1O may 1843; French won and took many prisonners to move them elswehere , but among them, the daughetr and the wife of Abd-el-Khader could escape with bedoins and the French troopps were too tired after the battle to reach them.
So to be the two composition could well represent the escape of the wife of Abd-el-Khader by his men from the French chasing them unsuccessfully. ...
More time needed to translate the text....
