the book with two stories of
submarines which will serve well to contrast Hun methods of sea
warfare with our own. The first story shows how those who manned the
German warships (one cannot employ the term "sailors" when speaking of
Germans) treated a British crew when it was at their mercy and could
not defend itself. The second story shows how our sailors acted in
similar circumstances.

In the summer of 1915 the submarine E13 was detached from the Harwich
Flotilla and sailed to the Baltic. She went aground off Saltholm, an
island in the Sound, near Copenhagen. A German destroyer came up and
opened fire on her while she thus lay helpless. The captain of the
submarine gave the order that she should be abandoned. This was done.
The Huns then opened a heavy fire with shrapnel and machine-guns on
the British sailors in the water, killing many of them. Shortly none
would have been left alive, and the E13 would have been added to the
list of the submarines that did not come back, their fate unknown, had
it not been for the providential appearance on the scene of a ship
belonging to a nation of real sailors, who have known the chivalry of
the sea from the earliest days. A Danish gunboat came up and placed
herself between the submarine and the German destroyer, thus
compelling the latter to cease firing. The Danes picked up the
survivors, who amounted to about one-half of the crew.

In a letter that appeared in the _Morning Post_, a correspondent gives
some further particulars of this incident:--"The Danish gunboat
compelled the Huns to cease firing on the defenceless crew of this
submarine, stranded in Danish territorial waters. Wanton murder was
added to the grave infringement of Danish territorial rights. Both the
Danish sailors and the gunners on the naval fort overlooking the scene
were burning with indignation, and were joyfully awaiting the order to
open fire on the German vessel, if the latter had not immediately
obeyed the Danish signal to stop these inhuman and illegal
proceedings. And the people of Copenhagen found it extremely difficult
to suppress their natural anger when the funeral of the victims took
place amidst scenes of heartfelt sympathy."

And now for the other story. One day in March 1915, while a section of
the Harwich Submarine Flotilla was outside the harbour, engaged in the
work of training men in the use of the torpedo, the _Firedrake_, one
of the three tender destroyers to the flotilla, sighted
