Chapter 3
The German Navy and the Evolution of Submarine Warfare
Although German Chancellor Otto von Bismarck had
chosen to concentrate on the German Army (and had deliberately avoided building
a navy for fear of antagonizing Great Britain), this policy changed after his
forced departure in 1890. Under the personal rule of Kaiser Wilhelm II
Germany embarked on an ambitious naval building program. In the mid 1890s
the Kaiser appointed Alfred Tirpitz as minister of marine with instructions to
build a navy second to none. Although Tirpitz spoke of a wanting only a
fleet large enough to protect German commercial interests, both he and the
Kaiser saw the navy as a means to conduct a dynamic world foreign policy (weltpolitik).
As the army built around the old Prussian Junker aristocracy had dominated in
the 19th century Tirpitz expected the German navy to play the key role of
Germany's expanding world role in the 20th century. His intention was to
create a fleet large enough to challenge the British for control of the seas
and world mastery. Tirpitz stated in 1897 that the Navy had become
"a question of survival" for Germany. He believed that the
navy, supported by the middle-class industrial German state, was the future, to
which eventually the army would have to give place.
Tirpitz believed that Germany had to prepare for a
showdown with the Anglo-Saxon powers. This would probably be decided in
one great naval battle in the North Sea or Atlantic between Germany on the one
side and either Britain or Britain and the United States on the other.
Ironically, this was precisely the scenario anticipated by English naval
leaders and it almost came to pass at Jutland in World War I.
Whereas the Kaiser had thought in terms of cruisers,
Tirpitz placed emphasis on the construction of battleships. His program
that passed the Reichstag in April 1898 called for the construction, by April
1904, of 19 battleships, 8 armored cruisers, 12 large, and 30 small cruisers.
Tirpitz was able to take advantage of the
international situation to add to the constructions program. A second
construction bill, which passed the Reichstag in June 1900 doubled the size of
the projected navy to a total of 38 battleships, 20 armored cruisers, and 38
light cruisers--all to be built within twenty years. This was in effect a
direct challenge to the Royal Navy Home Fleet, then about 32 battleships.
A naval building race between
German historian Gerhard Ritter has called the Tirpitz
plan a "gruesome error" and German naval policy in general, a
"monstrous error in judgement." It is hard to disagree with his
conclusion. Far From driving

German naval power was also nullified by the other
developments, such as the 1902 Anglo-Japanese treaty, which permitted British
naval reductions in
There were also limits as to what
With his attention fixed on battleships, Tirpitz was a
late convert to submarines. The submarine was a delivery system ideally
suited for the torpedo, although it was originally thought useful largely for
observation duties. The first practical submarine was developed by an
American, J. P. Holland, in the 1890s, and the employment of submarines
as naval weapons was pushed by the British and French rather than the German
navy. By 1899 the French had one with torpedo tubes in service. The
first German Unterseeboot, U-1, was not completed until the end of 1906 and it
was several years before its potential was realized. The 1912 budget
projected a total of 72 boats, but
In all navies, no less the German, only a minority of
naval officers saw the potential of the submarine at sea. As with most
new weapons its support came from a small faction of devotees. The
negative attitudes toward submarines were largely a result of conferences on
the laws and usages of war held during the first decade of the century.
Conferees agreed that submarines could only be used to attack enemy warships
and naval personnel. If used against commercial shipping submarines would
have to follow all of the same rules as surface ships. This meant
submarine captains would be forced to stop merchantmen, search them for
contraband of war, give crew and passengers time to abandon ship, and take
measures for their safety before firing torpedoes. While surfaced and
dead in the water, submarines were extremely vulnerable. for that reason,
commerce warfare was believed virtually out of the question.
Submarines were also not compatible with traditional
prize court practices. Relatively small craft, they lacked sufficient
crew size for proper visits and searches. Furthermore they were too small
to take aboard the crews of the ships they would stop. The most dreadful
fact to their commanders was their vulnerability during the long period of time
it took submarines to surface and submerge. The hassle and danger of
surfacing would lead submarine captains to fire torpedoes at targets without
surfacing to identify them, and this often ended in mistaken results.
The submarine phase of the war did not begin
well for
On September 5, however, U-21 sank a British
destroyer, the Pathfinder, patrolling off the Firth of Forth, the first
warship sunk by a submarine in the war. She went down with 259 men.
A far more graphic illustration of the submarine's potential came on September
22 when elderly U-9 sank three old British cruisers, the Cressy, Hogue,
and Aboukir, off the Dutch coast. The Aboukir was first to
be torpedoed. The captains of her sister ships thought she had been the
victim of a mine and stopped their ships dead in the water to take aboard
survivors, making them easy prey. The loss of 1,459 seamen (837 were
rescued) and three cruisers did not upset the naval balance but it clearly
signalled a new age in naval warfare.
The first demonstration of the lethal capabilities of
the submarine as a commerce raider occurred on
The first indication of the diplomatic repercussions
of submarine attacks occurred after the
The Glitra and Ganteaume helped draw the
attention of German naval officers to the submarine's worth as a weapons
system. Indeed U-boats were the most active and most destructive of all
classes of warships in World War I and they remained active until the end of
the war.
In 1914 the German submarines were tasked with
patrolling the
Attacks specifically on British merchantmen stopped
for a month after the Glitra incident. They began again on
November 23 with the sinking of the Malachite and continued on the 26th
with the loss of the Primo. These two attacks were isolated
incidents and not part of a larger German submarine campaign against
commerce. The German navy had not yet decided to undertake such a course.4
Commodore Bauer was the main proponent of a German
declaration of submarine warfare against commercial shipping. On October
8 he submitted such a recommendation to Commander of the German High Seas Fleet
Admiral Hugo von Pohl. Bauer called for an offensive campaign and greater
numbers of submarines. He felt the British mining of the approaches to
the English Channel warranted such action. But his proposal was rejected;
Pohl and others did not feel British mines alone justified a campaign in
violation of international law.
Bauer was not dissuaded; he knew others agreed with
him. For instance, in November Admiral Alfred von Tirpitz intimated to an
American correspondent the possibility of a submarine campaign as a test to
ascertain U.S. attitudes. When this interview hit the newspapers it
created a sensation in Germany and led to the formation of a "U-boat
party," which demanded unrestricted submarine warfare.5
Pohl was converted to Bauer's way of thinking after
the November 2 British proclamation of the entire North Sea as a British
military area. At the end of December Bauer again recommended a
submarines campaign, noting that Germany possessed sufficient submarines to
commence commerce raiding at the end of January. Admiral Reinhard Scheer
backed Bauer by submitting memoranda recommending a submarine blockade, viewing
it as the best way to bring the Royal Navy into battle.
Senior German Navy officers supported these
proposals. They too considered the British declaration justification for
unrestricted submarine warfare. This attitude, coupled with a
considerable agitation in the German press, brought about the German decision to
proclaim a blockade. On February 4 Berlin declared the north and west
coasts of France a war zone in which all Allied merchant vessels would be
liable to being destroyed.6
This was a landmark action. The German Government did not foresee the
anger and fear that this proclamation would ignite in the American
public. However naive it seems now, Americans then did not believe their
lives should be threatened at a time when their country was still
neutral. It was this belief in the absolute sanctity of neutrals that
made unrestricted submarine warfare the main cause of the United States
military intervention in World War I.
