Such as it was, however, says Mr Alison, the barrier required to be cut through; and Marlborough resolved to commence it with the siege of Kaiserworth, a place of very great importance. He took it--but at a cost of 5000 men; and then took Venloo, and finally Liege--all places, of extreme importance, and desperately defended; and with these feats he concluded the brief but brilliant, campaign which laid the foundation of all his future victories. It stripped the French of many of the chief advantages with which they had opened the war. He had broken through their line, so formidable for offensive and defensive war; he had "thrust his iron gauntlet," says Mr Alison, "into the centre of their resources." And the entire merit was his own, as Lord Athlone, his rival and second in command, thus nobly testified:--"The success of the campaign is entirely owing to its incomparable commander-in-chief; for I, the second in command, was, on every occasion, _of an opposite opinion to that which he adopted_!" His success was like a bright burst of sunshine over a long-troubled land! But here an incident occurred which might have ruined all. While dropping down the Meuse, on his return to England at the conclusion of the campaign, he was positively taken prisoner by a small French force,--whose commander, however, ignorant of the prize which was within his reach, and skilfully misled by a sagacious device of Marlborough's servant, suffered him to depart! The peril in which he had been spread consternation everywhere, equalled only by joy at his escape, which was powerfully expressed to him by the Pensionary Heinsius. "Your captivity was on the point of causing the slavery of these provinces, and restoring to France the power of extending her uncontrollable dominion over all Europe. No hope remained, if she had retained in bondage the man whom we revere as the instrument of Providence to restore independence to the greater part of the Christian world!" On what apparently trivial incidents often depend the greatest events that can happen to mankind! Marlborough was received with transports in England, and raised to the dukedom of Marlborough. The difficulties which the Dutch deputies had thrown in his way during the first campaign, owing, says Mr Alison, to timidity, ignorance of the military art, personal presumption, and the spirit of party, on several great occasions thwarted the most decisive measures of Marlborough,--but proved only a foretaste of what was in store for the harassed commander. Mr Alison gives an interesting letter which Marlborough wrote to his Countess, immediately on his arrival at the Hague. It is full of the passionate fondness of a lover to his mistress; yet was written by a man of fifty-two to a wife to whom he had been married twenty-three years! There are innumerable other instances, in these volumes, of the romantic fervour of their attachment. Such was Marlborough's first campaign,
