ty. The _Capella_
was one of the craft that picked up the welcome order.

She was now only seven sea miles distant from the Dean Tail Buoy.
Within ten minutes of the receipt of the wireless she was on the
spot--one of the very first of a regular hornet flotilla bent upon
adding yet another of Von Tirpitz's pets to the "bag".

For the next quarter of an hour it looked as if a novel kind of marine
waltz was in progress. Nearly a score of swift vessels were executing
fantastic movements at full speed, circling and interchanging positions
until it seemed as if collisions were impossible to avoid.

Their object was to thoroughly bewilder the already doomed U-boat, for,
if possible, her capture in a practically intact condition was desired.
In very deep water, salvage of a sunken submarine was out of the
question; here, in a comparatively shallow depth, and close to an
important naval base, to which the prize could be taken with little
trouble, the opportunity for capture rather than instant destruction
was too good to be missed.

Suddenly a cloud of white smoke shot up from the sea. Its appearance
was greeted by hearty cheers from the patrol vessels. It was a signal
that the U-boat, in her attempt to find deep water, had floundered
blindly into the trap. Over and over again the hunters passed, towing
non-explosive grapnels, until it was certain that the prey was helpless
in their toils.

Then, in obedience to an order from the senior officer, the swift
vessels withdrew for nearly three cables' length from the spot where
the boat lay. Two slow but powerfully engined trawlers approached at a
cable's length abreast, towing the bight of a massive steel hawser
between. Doing little more than drift with the tide they crept past
the submerged U-boat, one on either side of the mark-buoy that
indicated her position.

Presently the strain on the hawser increased. It was only by making
full use of the twin-screws that the trawlers were able to prevent
themselves from swinging together. The steel rope stretched until it
resembled two metal bars which bore silent testimony to the strain.

Just then the two vessels shot ahead. Although the hawser was still
intact, it no longer took any strain. But its work was done. The
bight, engaging the conning-tower of the unterseeboot, had turned the
submarine on its side. In the space of a few seconds the deadly fumes
from the capsized batteries had almost painlessly accounted f
