INTRODUCTION
Submariners are a race apart, even from their comrades who serve in surface
vessels. Early in the Second World War, an elite force of German submariners
known as the Ubootwaffe nearly perfected the underwater tactics of the First
World War U-boats to successfully sever Britain’s transatlantic supply lifeline.
To the Allies, these enemy sailors were on a mission that was unequivocally evil.
A popular fiction persists that the U-boat men were all volunteers; they were
not. But once committed to the Ubootwaffe, each man soon understood and
accepted that he would be a proud part of a unique brotherhood. Doing so was
essential; he was about to set out, in claustrophobic, unsanitary, hellish
conditions, on a voyage—an adventure—that would challenge and stretch his
mental and physical endurance to the very limits, one that he was unlikely to
survive. And, if he did return, he drew little comfort from family or friends,
trapped in the knowledge that another, possibly fatal patrol awaited him. The
men of the Ubootwaffe were linked together as comrades, by the ever-present
dangers of the enemy and the weather, and by their unity of purpose more
powerful than that of any other sailors.
All submariners are brave, no matter what cause they are fighting for. The
men of the Ubootwaffe were eventually beaten by the overwhelming industrial
and technological might of the Allies. Of the 39,000 men who went to sea in the
U-boats of the Second World War, 27,491 died in action and a further 5,000
became prisoners of war. Of the 863 German U-boats that sailed on operational
patrols in that war, 754 were lost.
Those who passed the training had to be the sort of men who did not mind
being unaware of where or why they were going when they sailed out of harbour,
who had never known claustrophobia, who could live in close proximity to forty
other men for up to three months at a time and who could spend four hours on
watch, lashed by icy winds, their eyes stung by salt spray, strapped or chained to
a deck rail or wire to avoid being swept away, and learning the truth of the old
sailor’s adage that “water is pointed.”
The men best suited for life aboard a U-boat were those who could sleep well
in a bed that was still warm and redolent of the man who last lay in it, and who
could stay in dreamland through the hissing of the inlet valves, the odd gurgle of
the bilge-pumps and the pounding of the pistons, and who would only be
awakened by the sound of depthcharges or the warning klaxon. They were those
who could tumble out of bed and scramble aft or forward like pieces of human
ballast when the commander ordered “Take her up!” or “Dive!”, who would be
ever keen for action, who could stay motionless and silent for hour after hour
while the depthcharges boomed around them and hurled the boat about, and
who never worried when their muscles began to atrophy from insufficient
exercise.
As the days went by, they got to know one another and their officers, and
began to realise that, although they were all individuals, each was now a part of
something more—a unit that was going to war. This was the touchstone that
helped them to become the sort of men they had to be. Not so much for love of
country, nor yet for love of family, but out of loyalty to the men they had trained,
messed and sailed with, and with whom they now shared their lives and fate.
