On 15 September 1916 tanks made their debut at Flers-Courcelette, one of the many engagements which took place during the Battle of the Somme.

The battle marked the beginning of a sorry chapter in British military history because the truth – a truth that to this day few seem prepared to acknowledge – is that the First World War tank was useless.

The list of its failings is lengthy. It was slow, it was unreliable, it had no suspension and it was horrible to operate. The temperature inside was typically over 100°F and as exhaust gases built up so crew effectiveness collapsed. It was also highly vulnerable. Field artillery could take it out easily. Even rifle ammunition could be effective against it. While normal bullets might not be able to penetrate the armour they could knock off small pieces of metal from the inside – known as spall – which then whizzed round the interior wounding all and sundry.

That the tank was the brainchild of Winston Churchill from his days as head of the Admiralty should have alerted senior commanders to the possibility that it was yet another of his crackpot schemes. But they persisted. For his part, Haig being a technophile put a huge amount of faith in the new invention. His diary is littered with references to the tank and he seems to have made great efforts to secure ever more of them. In consequence, huge amounts of effort went into a technological dead end when it would have been far better spent on guns, shells and fuzes.

Not that such efforts were ever likely to satisfy the snake-oil salesmen who made up the ranks of the tank enthusiasts. In the face of tank failure after tank failure they simply claimed that their beloved weapon just wasn’t being used properly.

Of course, like all good conmen they liked to take credit for other people’s successes. So, when a huge number of tanks were used at Cambrai in 1917 and the initial phases went reasonably well they were happy to put it all down to the tank. The fact that within 3 days an initial tank force in the hundreds had been whittled down to single figures by mechanical failures and withering German artillery fire was glossed over.

The credit should really have gone to the “predicted barrage”. As with so much to do with artillery this needs a little explaining. If your artillery barrage is to be effective you need to know where your shells are going to land. Although manufacturers attempt to build guns with uniform characteristics this is an extremely difficult thing to do. Worse still every time a gun is fired the barrel experiences wear and its characteristics change. Before Cambrai the answer had been “registration”. Guns would fire shells at the enemy and observers would spot where they landed. The drawback was that the enemy could tell that an attack was on its way. In a predicted barrage the gunners worked out in advance where the shells would land so the first the enemy would know about an attack was when he was hit by a full-scale barrage. This meant that for the first time since the beginning of the war surprise could be re-introduced to the battlefield.

Cheaper than a Great War tank and about as useful.
