lieved that more efficient hull subdivision, to minimize the flooding after
a torpedo hit, could easily be offset by the development of larger torpedo
warheads. According to Yarnell, the only defense against the torpedo was
speed, and when faced with a torpedo attack, the fleet would only achieve
victory if led by “an admiral, who realizing the danger, has the moral
courage to ignore it, accept the losses entailed, and push his fleet in to de-
cisive gun range and victory.”

Moral courage did not make battleships, or
soldiers, torpedo- or bullet-proof. One might excuse Yarnell’s bravado since
he was removed from the European land war and writing before Verdun
and the Somme, where courage, virility, and esprit d’corps failed to counter
the effects of the machine gun and artillery.

While Yarnell (a future ad-
miral) trusted courage, the Bureau of Construction & Repair placed its
trust in steel subdivision bulkheads and delayed the construction of battle-
ships 43 and 44 to make the hulls “torpedo-proof.”

In December 1916 Lieutenant (junior grade) F. A. Daubin first eluci-
dated a submarine with a mission subordinate to the battleship. In an apt
comparison, Daubin called for the construction of large submarines ex-
clusively since small, coastal defense submarines were as unnecessary as
coastal defense battleships.
56
Between August 1914 and February 1916, sub-
marines had sunk 487 vessels—the vast majority of which were merchant
ships. Daubin rejected the commerce raiding experience of the European
War, surprising given the parallel between the island empires of Japan and
the United Kingdom and American strategic concerns over Japan. Instead,
he argued for submarine employment in guerre d’escadre targeting enemy
warships. Daubin did offer guerre de course as a secondary mission, while
characterizing the European War as strangely inverted: “Abroad, it would
seem the secondary role has become the primary, or the submarine having
failed in its more important mission is doing what can be done within its
capacity against commerce.”
57
Daubin argued for the placement of fleet
submarines under the command of the fleet commander-in-chief, just like
the torpedo flotilla, so that the submarines’ “offensive power would be co-
ordinated with that of the fleet.”
58
Daubin’s article reflected the more realistic view that submariners could
only flourish if they presented their technology, not as a counter to the
battleship but as a supportive element within the hierarchy of the battle-
ship technological paradigm. According to Daubin, fleet submarines
would act as scouts searching out the enemy battleship fleet or populate
