Sketch Map showing complete investment of Tournai.
The fortifications of Tournai were excellent. Vauban had superintended that piece of engineering in person, and the scheme of the fortifications was remarkable from the strength of the citadel which lay apart from the town (though within its ring of earthworks) to the south. The traveller can still recognise in its abandonment this enormous achievement of Louis XIV.’s sappers, and the opposition it was about to offer to the great hosts of Marlborough and Eugene does almost as much honour to the genius of the French engineer as to the tenacity of the little garrison then defending it.
Two factors in the situation must first be appreciated by the reader.
The first is that the inferiority of Villars’ force made it impossible for him to do more than demonstrate against the army of observation. He was compelled to leave Tournai to its fate, and, indeed, the king in his first instructions, Villars in his reply, had taken it for granted that either that town or Ypres would be besieged and must fall. But the value of a fortress depends not upon its inviolability (for that can never be reckoned with), but upon the length of time during which it can hold out, and in this respect Tournai was to give full measure.
Secondly, it must be set down for the allies that their unexpectedly long task was hampered by exceptional weather. Rain fell continually, and though their command of the Scheldt lessened in some degree the problem of transport, rain in those days upon such roads as the allies drew their supplies by was a heavy handicap. The garrison of Tournai numbered thirteen and a half battalions, five detached companies, the complement of gunners necessary for the artillery, and a couple of Irish brigades—in all, counting the depleted condition of the French units at the moment, some six to seven thousand men. Perhaps, counting every combatant and non-combatant attached to the garrison, a full seven thousand men.
The command of this force was under Surville, in rank a lieutenant-general. Ravignon and Dolet were his subordinates. There was no lack of wheat for so small a force. Rationed, it was sufficient for four months. Meat made default, and, what was important with a large civil population encumbering the little garrison, money. Surville, the bishop, and others melted down their plate; even that of the altars in the town was sacrificed.
The first trench was opened on the night of the 7th of July, and three first attacks were delivered: one by the gate called Marvis, which looks eastward, another by the gate of Valenciennes, the third at the gate known as that of the Seven Springs. A sortie of the second of these was fairly successful, and upon this model the operations continued for five days.
By the end of that time a hundred heavy pieces had come up the Scheldt from Ghent, and sixty mortars as well. Four great batteries were formed. That to the south opened fire upon the 13th of July, and on the 14th the three others joined it.
The discipline maintained in the great camps of the besiegers was severe, and the besieged experienced the unusual recruitment of five hundred to six hundred deserters who penetrated within their lines. A considerable body of deserters also betook themselves to Villars’ lines, and the operations in these first days were sufficiently violent to account for some four thousand killed and wounded upon the side of the allies. Villars, meanwhile, could do no more than demonstrate without effect. Apart from the inferiority of his force, it was still impossible for him, until the harvest was gathered, to establish a sufficient accumulation of wheat to permit a forward movement. He never had four days’ provision of bread at any one time, nor, considering the length of his line, could he concentrate it upon any one place. He was fed by driblets from day to day, and lived from hand to mouth while the siege of Tournai proceeded to the east of him.
That siege was entering, with the close of the month, upon the end of its first phase.
