would in
any event devour all his warmth.

Repentantly, we had again picked up our thick camel's wool garments
which we had laid off in the southern waters. The further we went north,
the heavier the clothes that we donned.

In addition to the cold there came a storm, the like of which I had
never seen during my entire service on the sea, and to describing which
I will devote a few lines, because a storm on a U-boat is altogether
different from a storm at sea in any other vessel.

The barometer had been uncertain for two days. Its hasty rising and
falling in accordance with the changes of the atmosphere made us suspect
we would soon get rough weather. It was the night between April
twenty-fourth and twenty-fifth. We traveled submerged to a considerable
depth, and I was lying in my bunk asleep, partly undressed. At about two
o'clock I was awakened and received the report:

"Lieutenant Petersen asks that the Captain-Lieutenant kindly come to the
'Centrale,' as it is impossible for him to steer the boat any longer
alone."

I threw on my jacket and hurried for the stern. On my way, on account
of the heavy rolling of the boat, I realized what was the trouble. There
must be a terrific storm above accompanied by a sea which only the
Atlantic could stir up.

Lieutenant Petersen confirmed my opinion of the conditions which had
developed during the night and added that he had never had so much
trouble with the diving rudder before in his life. This meant a great
deal, for Petersen was with me when our U-boat had been equipped for
service for the first time, and had already gone through all kinds of
weather. In spite of all the watchfulness that he and the well-trained
crew used, the diving rudder's pressure was not powerful enough to
resist the enormous strength of the waves. The boat was tossed up and
down as if she had no rudder whatever. Only after we had submerged
twice as deep as we had been were we able to steady the boat to any
degree. We could still feel the force of the sea and knew the storm must
be terrific.

When, at daybreak, we arose to the surface there was no chance to open
the hatches. The opal green mountains of waves came rolling and foaming
at us. They smothered the boat with the great masses of water, washed
completely over the deck and even up over the tower. If any one had
dared to open the hatch and go out on the conning tower, he would
certainly have been lost. I was standing at the periscope and
