Trenchard in the Trenches

An earlier post on Trenchardism naturally prompts this early modernist to muse on the early modern art of bombing civilians. Consider it a late Christmas present.

Like many aspects of warfare, the early modern art of bombardment was quite similar to the theory and practice of its modern counterpart, only on a smaller scale. The practice of launching nasty objects over tall walls is as old as catapults, and it has always been easier to hit the broadside of a town than precisely strike a specific point on a wall. Almost as soon as gunpowder weapons made their appearance in 14th century Europe, warmakers envisioned their use against towns. As powder and projectiles increased in performance and availability, gunners targeted the inhabitants of fortified places as well as the walls they sheltered behind. Solid shot could pulverize stone walls, while iron cannonballs heated glowing red over an iron grate (“red-hot shot”) threatened to set buildings ablaze inside the town. In the 16th century, the parabolic trajectory of bombs fired from mortars made bombardment more efficient, particularly after bombardiers (eventually) figured out how to light the bomb fuse from the ignition of the main powder charge in the tube. Ever-growing arsenals, supplemented by yet more technological advances, significantly expanded the use of bombs throughout the 17th century: the French development of the bomb ketch under Louis XIV made coastal bombardments a more practical matter; howitzers’ arcing trajectories could also target the interior of a town; while the development of the man-portable Coehoorn mortar allowed thousands of double-grenades to rain down on a besieged garrison, and any unfortunate inhabitants as well. A few other “inventions” were even more fanciful. As one 1688 periodical reflected on the state of the early modern military art:
But this Age affords more refined Wits, and better fitted for Malice. They have invented Bombs, Balls and Carcasses, full of all nocent [harmful] things, Nails, Knives, Sharp-pointed Contrivances, Grapples, Pistols firing, and several other Diabolical Inventions; which shot up into the Air from the Mouths of the Brass Mortar-pieces, upon their falling burst with such a Violence, as immediately occasions a Total Ruine among the Besieged, and to their Houses; and when the Cities, are of a small Extent, their Havock and Destruction presently forces them to lay down their Arms, and no longer to resist their fury.
But of all Inventions of this Nature, that seems most marvellous of certain Mortar-pieces, which by the force of people and Instruments fill’d with Wind, throw certain great Bombs made of six round and Convex Iron Plates, wherein are contain’d twenty five persons well provided with Arms. These Bombs may be shot into the Enemies Fortresses four times in an hour, and by this means fill them so invisibly with such a vast number of Soldiers, (since twelve Mortar-pieces of the same Bulck will be discharg’d each time) that the Place will be presently taken; for their Sergeants can in an Instant draw them up in good order, and make them seize on the Sentinels and Guards, and by this means obtain a more certain Victory, then ever did the Romans by their Bucklers, or Clypeus Contextus, since they can enter the Towns without any resistance.” Early modern air cavalry, Trojan Horse style.

Bombardment technology developed slowly, but the justifications for the semi-indiscriminate attack on civilian population centers remained constant, and are familiar to us today. Most garrisons were quartered among urban civilian populations, and while mortar fire might have been relatively accurate, the ability to distinguish military from non-military targets within a town was limited. Nor was such discernment a priority, since early moderns believed that the bombardment of towns could achieve positive tactical objectives. First, indiscriminate bombardment was used as a threat – declare your neutrality, deliver up the demanded ransom, and nobody needs to get hurt. If compliance was too long in coming, or perhaps if a message needed to be sent, bombardment might serve as a punishment, witness Louis XIV’s 1684 bombardment of Genoa, an Italian port-state that had dared to assist France’s Spanish enemy. On a narrower tactical level, as our quote above suggests, targeted bombardment of a garrison’s barracks and posts might sap the defenders’ morale. But more widespread destruction could also cause the enemy harm – whether the intent was to burn the fodder magazines and mills within the town, or to create a more general conflagration that damaged the enemy’s ability to continue the war through lower tax revenues and destroyed infrastructure. In wars of attrition, such destruction could be its own objective. But, fortunately for contemporaries, this was not the age of the chevauchée: bombardment was rarely used with wild abandon, likely due only in part to the arguments of the cooler heads, who noted that destroying too many towns made little sense if the attacker intended to occupy them and extract their resources.

Even though early moderns refrained from spreading fire and death across the enemy’s lands as a matter of course (at least after the Thirty Years War), the tactical application of bombardment was standard practice. The need for speed encouraged most besiegers to accelerate their attacks by lobbing exploding carcasses in among the townspeople. Besieged burghers, after all, were just as ‘guilty’ for allowing garrison troops to continue their defense, even if they didn’t actively support the garrison. The suffering of innocents appears to have been a non-issue for most military practitioners well into the 18th century, and for many civilian observers as well. Neither Louis nor his Secretary of War Louvois apparently gave much thought to the civilian casualties caused by the bombardment of Luxembourg, nor did the English overly concern themselves about the citizens of Saint-Malo, Dieppe or Dunkirk – the inhabitants of these ‘pirate nests’ facilitated the war effort, and they further benefited economically from the prizes captured by French privateers.

Not even the Christmas season overrode such military expediency. Towards the end of December 1708 the Duke of Marlborough received a civilian deputation from the besieged town of Ghent (population 51,000) begging him to save their homes from destruction. Grinch that he was, the Duke informed them that “since they had brought this misfortune upon themselves by their own folly or negligence [Ghent had had a small British garrison in its castle that was surprised earlier in the year], they must either assist us against the garrison or expect we should use all manner of extremity to reduce them to their duty.” Red-hot shot pelted the town for several hours until the French garrison beat the chamade and negotiated their surrender. Civilian suffering wasn’t always the primary objective of early modern bombardment, but it often was a supplemental tactic. Humanitarianism rarely provided a check on such methods.

Same as it ever was, just on a smaller scale. Like modern airpower theorists, early moderns sometimes hoped that a massive bombardment of the enemy capital would quickly force them to their knees, and on rare occasions it might actually work (as with Genoa in 1684 and Algiers the same year). More often, however, early modern bombardment was intended to terrorize the civilian population on a city-by-city basis, usually coupled with an attempt to capture the town. As so often happens, military capability slides inevitably into military use, with theoretical limitations on war preempted by immediate military expediency. Whether a Coehoorn mortar, a B-29 or a Predator drone, it’s usually easiest to shoot first, and chalk up ‘collateral damage’ to the vagaries of war.

With my apologies–updates to the blog platform have made it more difficult to deal with images, which Dr. Ostwald has included in this posting on his own site.  They are great visuals that add a great deal to his point, so I respectfully direct your attention thataways.–M.S.
