Naturally, when a submarine is pursued she can drop under
the surface and leave no trail. But suppose a single submarine
to be guarding a harbor, unaided by other fighting craft. A twenty-or
twenty-two knot battleship is discovered, trying to make the harbor.
Even if the battleship steams away the submarine should be capable
of following. The engines of the 'Dodger,' in favorable weather,
can drive her at twenty-six knots on the surface."
"She's as fast as a torpedo-boat destroyer, then, sir," hazarded Dan.
"Yes; and the submarine needs to be as fast. With the improvement
of submarine boats the old style of torpedo boat will pass out
altogether. Then, if the destroyer is retained the submarine
must be capable of attacking the destroyer on equal terms. Undoubtedly,
after a few years more the river gunboat and the submarine torpedo
boat will be the only small fighting craft left in the navies of
the leading powers of the world."
Even while this brief conversation was going on the speed of the
"Dodger" had begun to increase again. Ensign Hasting's head showed
through the opening in the conning tower.
"We're going now at a twenty-knot clip, sir," Hal reported. "Do
you wish any more speed?"
"Not in Chesapeake Bay; navigating conditions are not favorable."
"Very good, sir." Hal vanished below. Never very talkative, Hal
was content to stand by his engines in silence when there was no
need of talking.
