Quotation from: Out of Time's Abyss

Written by: Edgar Rice Burroughs

Bradley knew nothing of the disappearance of Bowen Tyler and Miss
La Rue, nor of the perfidy of the Germans in shelling the fort
and attempting to escape in the U-33; but he was in no way
surprised at what he saw before him.

The little party came slowly onward, the prisoners staggering
beneath heavy cans of oil, while Schwartz, one of the German
noncommissioned officers cursed and beat them with a stick of
wood, impartially. Von Schoenvorts walked in the rear of the
column, encouraging Schwartz and laughing at the discomfiture of
the Britishers. Dietz, Heinz, and Klatz also seemed to enjoy the
entertainment immensely; but two of the men--Plesser and Hindle--
marched with eyes straight to the front and with scowling faces.
