Tournai once more passed into the hands of the French in 1668, when it was captured by Louis XIV and afterwards elaborately fortified by Vauban, was retaken by Marlborough in 1709, returned to Austria five years later, and captured once more by the French after the battle of Fontenoy in 1745. Four years later it was again restored to Austria, but was twice taken by the armies of the first French republic, remaining French territory till the battle of Waterloo. It would be a difficult matter to say how often its fortifications have been built, demolished, rebuilt and again destroyed. The most noteworthy of these later sieges was that of 1745, during the War of the Austrian Succession, which brought the English and French into conflict even along the frontiers of their far-off American colonies. Austrian Flanders became the arena of the decisive campaign in this war--in which its inhabitants had absolutely no interest or concern whatever--and Tournai was the prize for which the armies fought. It was during this and the preceding century that Flanders became "the cockpit of Europe"--foreign armies sweeping over its fertile plains in wars the very purpose of which was unknown to the peasants who helplessly saw their cattle and crops swept away and their farmsteads and villages destroyed. It is curious to remark how frequently the English were engaged in these conflicts, particularly in the vicinity of Tournai. In the words of Lord Beaconsfield, "Flanders has been trodden by the feet and watered with the blood of successive generations of British soldiers." An English force formed the nucleus and the backbone of the allied army, which was commanded by the Duke of Cumberland, brother of King George II. The French forces were led by Maurice de Saxe, the greatest military leader of that generation, as Marlborough had been of the one before it. King Louis XV--for almost the only time in his long reign--played the part of a man throughout this campaign. When Saxe explained his plan of campaign, which involved a scheme of field fortifications, the "carpet generals" protested loudly that Frenchmen were well able to meet their foes on open ground. Louis silenced these arm-chair critics and replied to his great field-marshal, "In confiding to you the command of my army I intend that every one shall obey you, and I will be the first to set an example of obedience."
