Exactly seventy years ago, in late November and early December 1936, Madrid was being bombed. The way Antony Beevor describes it, it was the first attempt at something like a knock-out blow:
The nationialists' failure to break through on 19 November made Franco change his strategy. He could not risk any more of his best troops in fruitless assaults now that a quick victory looked much more difficult. So, for the first time in history, a capital city came under intense air as well as artillery bombardment. All residential areas except the fashionable Salamanca district were bombed in an attempt to break the morale of the civilian population. The Italian Aviazione Legionaria and the Luftwaffe conducted a methodical experiment with their Savoia 81s and Junkers 52s. The bombing did not, however, break morale as intended; on the contrary, it increased the defiance of the population. In London, Prince Otto von Bismarck, the German chargé d'affaires, derided British fears of air attacks 'since you see what little harm they have done in Madrid'. 1
My first instinct was to scoff. The first capital to undergo intense aerial bombardment? London was bombed in 1915; Paris in 1914. But the key word is 'intense'. In the First World War, the only period when London was bombed repeatedly was at the end of September and start of October 1917, when Gothas and Zeppelins attacked on six nights out of nine. It sounds like the raids on Madrid were much more frequent than that, and they were certainly heavier: the Condor Legion dropped 36 tons of bombs on 4 December alone, about a tenth of the total dropped on Britain during the whole First World War. Casualties don't seem to have been markedly greater, though: nearly 100 deaths in those six London raids, maybe twice that in the Madrid ones (though contemporary reports gave higher estimates).
On balance, Beevor's claim is probably a fair one. But regardless, the Spanish Civil War was certainly hugely important as far as the development of military aviation is concerned. Whereas Lenin had arrived at Finland Station by steam train, Franco now flew about in a Dragon Rapide. Famously, Franco's rebellion was assisted in its very early stages by a strategic airlift across the Straits of Gibraltar (in German aircraft) of the battle-hardened Army of Africa (though Beevor argues that this was not decisive, as the troops would have been ferried across by sea if air transport had not been available). Close air support played a critical role in many ground battles, while overhead, ideas about aerial combat in the age of fast monoplanes were put to the test. Italy, Germany and the Soviet Union all got a chance to try out their latest aircraft in field conditions, including the German Me 109, He 111, and Ju 87. And, as well as Madrid, many cities, towns and villages were bombed throughout the war, often in relation to a ground offensive rather than as a pure strategic bombardment. Some incidents stand out for their ferocity: Guernica, of course, in April 1937, but also another Basque town, Durango, the previous month; Alcañiz in Aragon, March 1938 (which Beevor describes as Italy's Guernica); and Barcelona, also in March 1938.
This last was chronicled by the British journalist John Langdon-Davies, a correspondent for the News Chronicle, in his book Air Raid: The Technique of Silent Approach, High Explosive, Panic. By his account, some 3000 people were killed in the raids of 16, 17 and 18 March 1938, with 5000 seriously wounded. Below is a photograph from Air Raid showing a Barcelona street scene after one raid -- the only exception to his stated avoidance of showing picture after picture of dead bodies:
Langdon-Davies claimed -- I don't know if it is actually true, but others at the time said the same thing -- that the Italian raiders had switched off their engines some distance out from Barcelona, glided in, dropped their bombs and then started up their engines again to make good their escape. The point of this was to minimise the warning time given by the acoustic detectors which ringed the city, giving fighters little chance to intercept and civilians little time to get to shelters -- thereby dramatically increasing panic. The bombers also returned at frequent intervals in order to maximise the psychological distress:
In short, twenty-six minutes of visits from half a dozen bombers themselves scarcely in danger destroyed the whole mental life of a million and a half people for forty hours. 2
Ultimately, Langdon-Davies believed that such tactics might well be employed against the British people, and this was the point of his book, for he believed Britain's ARP measures were out-of-date in light of the "silent raids" in particular and the Spanish experience more generally.
James Corum has argued that the RAF, like other western air forces, learned little from the air war in Spain. 3 It does seem that British observers went out of their way to deny the general ineffectiveness of morale bombing and of unescorted bombers. For example, Wing Commander R. V. Goddard, who had himself travelled to Spain on a fact-finding mission, reported that attacks on one factory had affected neither production nor worker morale, despite the destruction of their homes and lives. But he explained this away as follows:
[I]t must be hard for people of a gay temperament to take a morbid view of things in the halcyon sunshine which seems to prevail nine days out of ten in Spain. The shattered steel works at Sagunto would have seemed very depressing in the wet and gloom of Sheffield, but in Spain it was not so. 4
So perhaps global warming will finally make Britain safe against the knock-out blow!
More seriously, I wonder if this picture of British blindness isn't somewhat exaggerated. Malcolm Smith has argued that a December 1937 report of Sir Thomas Inskip, Minister for Defence Co-ordination (infamously, amusingly and I think unfairly likened to Caligula's horse by Cato in Guilty Men) forced a shift in emphasis in home defence: away from Bomber Command as a deterrent and towards Fighter Command as a shield. According to Smith, this was partly for financial reasons but mainly because several years of expanding the RAF's bomber force had failed to prevent Luftwaffe expansion. 5 It doesn't seem that Inskip referred to evidence from the Spanish Civil War, but I find it interesting that around this same time, books on aerial warfare written for the public start to display much more scepticism about the possibility of a knock-out blow. Partly this was due to the presumed security afforded by ARP; partly due to the resilience of Spaniards under air attack; but most of all, it seems to me, is the upgrading of the prospects of the fighter based on evidence from Spain (and now also China). As Major-General Henry Rowan-Robinson noted, 'Recent information, however, though nebulous in the extreme, indicates that [fighters] are now in the ascendant'. 6 Perhaps Inskip was influenced towards knock-out blow scepticism by the Spanish example, too -- though if the famous bout of trench-digging in London parks in September 1938 is any guide, the British public was not.
