The prime agent of death was unquestionably tuberculosis. When one looks around Western Europe today, where TB sanatoria are a happily and rapidly vanishing species, it is difficult to imagine just how terrible a scourge tuberculosis was just over a generation ago. It is not that tuberculosis, worldwide, has been eliminated: in many underdeveloped countries it still remains that same terrible scourge and the chief cause of death, and as recently as the early years of this century TB was still the number one killer in Western Europe and North America. Such is no longer the case since scientists came up with the agents to tame and destroy the tubercle bacillus. But in 1939 it was still very much the case: the discovery of the chemotherapeutic agents, rifampin, para-aminosalicylic acid, isoniazid and especially streptomycin, still lay far beyond a distant horizon.
It was upon those tuberculosis-ridden seamen, ill-housed and abominably fed, that Britain depended to bring food, oil, arms and ammunition to its shores and those of its allies. It was the sine qua non conduit, the artery, the lifeline upon which Britain was absolutely dependent: without those ships and men Britain would assuredly have gone under. It is worth noting that those men’s contracts ended when the torpedo, mine or bomb struck. In wartime as in peacetime the owners protected their profits to the bitter end: the seaman’s wages were abruptly terminated when his ship was sunk, no matter where, how, or in what unimaginable circumstances. When an owner’s ship went down he shed no salt tears, for his ships were insured, as often as not grossly over-insured: when a seaman’s ship went down he was fired.
The Government, Admiralty and ship-owners of that time should have been deeply ashamed of themselves: if they were, they manfully concealed their distress: compared to prestige, glory and profits, the conditions of life and the horrors of death of the men of the Merchant Navy were a very secondary consideration indeed.
The people of Britain cannot be condemned. With the exception of the families and friends of the Merchant Navy and the splendid volunteer charitable organizations that were set up to help survivors—such humanitarian trifles were of no concern to owners or Whitehall—very few knew or even suspected what was going on.
2 As a lifeline, a conduit and an artery, the Liberty Ships were on a par with the British Merchant Navy: without them, Britain would have assuredly gone down in defeat. All the food, oil, arms and ammunition which overseas countries—especially the United States—were eager and willing to supply were useless without the ships in which to transport them. After less than two years of war it was bleakly apparent that because of the deadly attrition of the British Merchant fleets there must soon, and inevitably, be no ships left to carry anything and that Britain would, inexorably and not slowly, be starved into surrender. In 1940, even the indomitable Winston Churchill despaired of survival, far less ultimate victory. Typically, the period of despair was brief but heaven only knew that he had cause for it.
In nine hundred years, Britain, of all the countries in the world, had never been invaded, but in the darkest days of the war such invasion seemed not only perilously close but inevitable. Looking back today over a span of forty and more years it seems inconceivable and impossible that the country survived: had the facts been made public, which they weren’t, it almost certainly would not.
British shipping losses were appalling beyond belief and beggar even the most active imagination. In the first eleven months of the war Britain lost 1,500,000 tons of shipping. In some of the early months of 1941, losses averaged close on 500,000 tons. In 1942, the darkest period of the war at sea, 6,250,000 tons of shipping went to the bottom. Even working at full stretch British shipyards could replace only a small fraction of those enormous losses. That, together with the fact that the number of operational U-boats in that same grim year rose from 91 to 212 made it certain that, by the law of diminishing returns, the British Merchant Navy would eventually cease to exist unless a miracle occurred.
The name of the miracle was Liberty Ships. To anyone who can recall those days the term Liberty Ships was automatically and immediately linked with Henry Kaiser. Kaiser—in the circumstances it was ironic that he should bear the same name as the title of the late German Emperor—was an American engineer of unquestioned genius. His career until then had been a remarkably impressive one: he had been a key figure in the construction of the Hoover and Coulee dams and the San Francisco bridge. It is questionable whether Henry Kaiser could have designed a rowing-boat but that was of no matter. He almost certainly had a better understanding of prefabrication based on a standard and repeatable design than any other person in the world at the time and did not hesitate to send out contracts for part-construction to factories in the United States that lay hundreds of miles from the sea. Those sections were transmitted to shipyards for assembly, originally to Richmond, California, where Kaiser directed the Permanente Cement Co., and eventually to other shipyards under Kaiser’s control. Kaiser’s turnover and speed of production stopped just short of the incredible: he did for the production of merchant vessels what Henry Ford’s assembly lines had done for the Model T Ford. Until then, as far as ocean-going vessels were concerned, mass production had been an alien concept.
Mistakenly, but understandably, there existed a widely-held belief that the Liberty Ships originated in the design offices of the Kaiser shipyards. The design and prototypes were, in fact, English and were conceived by the design staff of the shipbuilders J.L. Thompson of North Sands, Sunderland. The first of what was to become a very long line indeed, the Embassage, was completed in 1935—the prefix ‘Liberty’ did not come into existence for another seven years, and only for some of the Kaiser-built vessels. The Embassage, 9,300 tons, with a raked stem and rounded stern and three triple-expansion coal-burning engines, was a non-starter in the æsthetic stakes, but then J.L. Thompson were not interested in æsthetics:what they had aimed at was a modern, practical and economical cargo vessel and in this they succeeded admirably. Twenty-four more similar vessels were built before the outbreak of war.
Those ships were built in Britain, the United States and Canada, the great preponderance in the Kaiser yards. Hull designs remained identical but the Americans, and only the Americans, introduced two changes which they regarded as refinements. One of those changes, using oil instead of coal as fuel, may well have been: the other, which concerned the accommodation of officers and crew, was not. While the Canadians and British retained the original concept of having the living quarters both fore and aft the Americans elected to have all the crew, officers and men—and the navigating bridge—in a superstructure surrounding the funnel. In retrospect—hindsight and bitter experience make for a splendid conductor to belated wisdom—it was a blunder. The Americans had all their eggs in one basket.
Those vessels were armed—after a fashion. They had four-inch low-angle and twelve-pounder anti-aircraft guns, neither of which was particularly effective, together with Bofors and rapid-firing Oerlikons: the Oerlikons were deadly in trained hands—but there were few trained hands around. They also had weird devices such as rocket-fired parachutes and cables carrying coils of wire and grenades: these were as dangerous to those using them as the aircraft they were supposed to bring down. Some few of these ships had catapult-launched Hurricane fighters—the nearest equivalent to the suicidal Japanese kamikaze planes that Britain ever had. The pilots could not, of course, return to their ships: they had the uncomfortable option of either baling out or ditching. In the Arctic, in winter, their survival rate was not high.
3 From the air, on the sea and under the sea the Germans, often with brilliance, always with tenacity and ruthlessness, used every means in their power to destroy the Merchant Navy convoys.
Basically, they used five main types of aircraft. Their standard or conventional bomber was the Dornier which flew at pre-determined heights and released their bombs in pre-determined patterns: they were useful planes and had their successes but were not particularly effective.
Much more feared, in ascending order, were the Heinkel, the Heinkel III and the Stuka. The Heinkel was a torpedo-bomber, which attacked at wave-top level, its pilot releasing the torpedo at the last possible moment, then using the lightened weight of his aircraft to lift over the ship it was attacking. Those planes had an unusual degree of immunity from destruction: when the anti-aircraft gunners on the merchant ships peered over the sights of their Oerlikons, Bofors or pom-poms—two-pounders—the thought that ‘He gets me or I get him’ didn’t make for the degree
