hward, the raider made her next and last appearance
on the morning of November 9 off the British cable and wireless
station on the Cocos Islands. As she approached, word was promptly
cabled to London, Adelaide, and Singapore, and--more profitably--was
wirelessed to an Australian troop convoy then only 45 miles away. The
_Emden_ caught the message, but nevertheless sent a party ashore,
and was standing outside when the armored cruiser _Sydney_ came
charging up. Against the _Emden's_ ten 4.1-inch guns, the _Sydney_
had eight 6-inch guns, and she was at least 4 knots faster. Outranged
and outdone in speed, the German ship was soon driven ashore in a
sinking condition, with a funnel down and steering gear disabled.
During her two months' activity thus ended, the _Emden_ had made
21 captures, destroying ships and cargoes to the value of over
$10,000,000.

The other German cruisers were also short-lived. The _Karlsruehe_,
after arming the liner _Kronprinz Wilhelm_ off the Bahamas (August
6) and narrowly escaping the _Suffolk_ and the _Bristol_ by
superior speed, operated with great success on the South American
trade routes. Her disappearance--long a mystery to the Allies--was
due to an internal explosion, just as she was about to crown her
exploits by a raid on the island of Barbados. The _Koenigsberg_,
on the east coast of Africa, surprised and sank the British light
cruiser _Pegasus_ while the latter lay at Mombasa, Zanzibar, making
repairs. She was later bottled up in the Rufigi River (October
30) and finally destroyed there (July 11, 1915) by indirect fire
from monitors, "spotted" by airplanes.

Of the auxiliary cruisers, the _Kaiser Wilhelm der Grosse_ was
sunk by the _Highflyer_ (August 26), and the _Cap Trafalgar_
went down after a hard fight with the _Carmania_ (September 14).
The _Prinz Eitel Friedrich_, which had entered the Atlantic with
von Spee, interned at Newport News, Virginia, in March, 1915, and
was followed thither a month later by the _Kronprinz Wilhelm_.

The results of this surface warfare upon commerce amounted to 69
merchant vessels, totaling 280,000 tons. With more strict concentration
upon commerce destruction, and further preparations for using German
liners as auxiliaries, the campaign might have been prolonged and made
somewhat more effective. But for the same purpose the superiority
of the submarine was soon demonstrated. To tak
