Urban Warfare in the Eighteenth Century

Dear Reader,

Today, we are going to examine an understudied topic in eighteenth-century military history: urban warfare. Although the eighteenth century was an age where generals preferred to fight large field battles and conduct formal sieges, the century did indeed see its share of urban warfare, that is to say, troops fighting house to house in built-up areas. Troops would occasionally find themselves fighting in village houses during large field battles, but addressing that is not the main goal of my post today. Rather, I seek to understand what happened when armies clashed in actual urban environments, towns or cities as they would have been identified in the eighteenth century.

Encounters of this sort are rare, but not unheard of. Principally, in writing this post, I examined the fight at Preston in 1715, the Austrian attack on Velletri in 1744, and the American assault on Quebec in 1775. At Preston, the Hanoverians attacked a unfortified town that a small Jacobite army had hastily attempted to barricade. At Velletri, an Austrian army attempted to capture the entourage of the future King Charles III of Spain. At Quebec, an initially successful assault on a fortified city bogged down in heavy street fighting. These experiences will be supplements by descriptions of village fighting in larger field battles. With these sources of experience in mind, what common experiences can we identify between these actions?

When fighting in an urban environment, soldiers quickly sought out cover, usually by barricading themselves in houses. At Preston in 1715, when the Jacobite commander William  MacIntosh was asked why he chose to defend Preston rather than a nearby ridge, explained, "the body of the town was the security of the army."[1] At Velletri in 1744, civilians, seeing the fire that Austrian troops were spreading in the town, began firing at the troops in the street from barricaded houses. The Austrians soon followed suite, taking cover in whatever houses they could force open.[2] Events followed the same pattern at Quebec in 1775, when French civilians, loyal to the crown, opened fire on rebel troops marching through the lower town. In the words of a junior British officer observing the scene, "some of the French who took to the houses... ke[pt] gauling them so as obliged the rebels also to take to the houses... where they remained and returned our fire."[3] Larger buildings were valued as observation points and firing platforms.[4] At confused fighting at Leuthen and Hochkirch in the Seven Years War, Austrian and Prussian soldiers sought any cover they could find, and used a high churchyard walls in these villages as miniature fortresses.[5] At the Battle of Blenheim/Höchstadt in 1704, the French attempted to use the village of Blenheim (Blindheim) itself as a strongpoint.[6]

In addition to houses, soldiers constructed street barricades and fighting positions. Searching for cover, soldiers used whatever they could find in order to provide cover for themselves. John Deane helpfully lists the materials used for the construction of street barricades at Blenheim: "trees, planks, coffers, chests, wagons, carts and palisades[.]"[7] At Leuthen in 1757, Austrians troops were told off, in the midst of battle, to construct fighting positions in the village.[8] At Preston in 1715, the Jacobites constructed numerous barricades across the streets, encompassing multiple lines of defense. In a running battle that lasted for days, the Hanoverians followed suit by building trenches and barricades of their own.[9] At Preston, some of these barricades were large enough for hundreds of men to take shelter behind.

In the course of the natural use of houses as cover by soldiers, structures were almost always burned. Fire had important tactical uses in the eighteenth century. Obviously, only immobile and suicidal men would remain in a burning structure during a fight, and many wounded men burned to death in these horrible encounters.[10] Soldiers set buildings on fire intentionally, in order to drive out defenders, at Preston and Velletri.[11] Fire, of course, spread unintentionally from there. Soldiers also believed that the smoke that fires generated could be employed as cover, essentially as a smoke screen. At Blenheim in 1704, and Preston in 1715, fires were intentionally set to give concealment to friendly forces. At Blenheim, John Deane relates that, "The village was sett on fire before we came to it by the enemy whereby they though to have blinded our gunners[.]"[12] At Preston, both the Hanoverians and the Jacobites used the smoke of burning buildings as cover, and may have set fire intentionally for that purpose.[13]

The Battle of Quebec, F. H. Wellington

In this urban setting, artillery played the role of supporting weapons, clearing streets, and demolishing enemy strongpoints.  Thomas Ainslee, a British officer at Quebec in 1775, described the process of taking a large house on a city street with American rebel troops inside:

Capt. Nairn...had by this time run up a ladder and entered a window at the end of the corner house where the enemy were posted, there they killed one and took another prisoner and my detachment in the other street having by my direction enlarged the post of one of the guns... brought it to bear on the house where most of them were. I ordered it to be fired and as it was loaded with canister and grape shott, it killed Capt. Hendrick of the Rifllers, wounded Capt. Lamb... and several others in the room all of these circumstances together... obliged them to lay down their arms and surrender.[14]

At Trenton in 1776, the American continental army used artillery to stop enemy movement on village streets, this tactic was also used by the Austrians at Hochkirch in 1758.[15] At Preston in 1715, cannons were used extensively to sweep streets of enemy forces, as well as fire on and demolish enemy strong points.[16] Henry Knox's suggestion to use artillery on the Cliveden at Germantown in 1777 may fit into this type of tactical thinking.

Heavy fighting in an urban setting usually led to a high number of enemy troops surrendering, when cover and dense terrain meant that flight was impossible. At Preston in 1715, the battle ended when after four days of resistance, the entirety of the Jacobite Army surrendered.[17] At Velletri, the fighting in the town netted the Austrians almost 600 prisoners. [18] At Quebec in 1775, more than one third of Montgomery's initial force, over 400 men, were captured by the British and their Canadian allies.[19]

Finally, the consequences for the urban environment involved in the fighting were usually severe. At Velletri in 1744, civilians were accidentally shot on one occasion, and looting by Austrian Grenzer was widespread.[20] In Preston, the prolonged nature of the fighting caused widespread destruction, and a commission for civilian relief set up after the end of hostilities received 226 requests from the inhabitants of Preston for relief, totalling sums of approximately £6,500, or approximately $850,000 today.[21]

Fighting in an urban environment was provided eighteenth-century soldiers with an odd mix of contradictions. In dense terrain, soldiers were more likely to have an abundance of cover, and use that cover effectively. Fire was used both offensively and defensively, to provide cover from the enemy, and drive the enemy from buildings. Artillery was employed with an impressive degree of tactical flexibility,  to control enemy movement and reduce enemy strong points. Finally, despite the greater cover afforded by urban environments, soldiers were much more likely to be captured by the enemy in large numbers if they lost the engagement. Fighting in urban environments also had the possibility of causing great damage to civilian property.  By and large, eighteenth-century warfare in an urban environment possess more than a passing continuity to the experiences of urban warfare in the modern world.
