Worn out with these long delays, Marlborough at length resolved at all hazards to pass the river, trusting that the Dutch, when they saw the conflict once seriously engaged, would not desert him. But in this he was mistaken. The Dutch not only failed to execute the part assigned them in the combined enterprise, but sent information of his designs to the enemy. The consequence was, Villeroi was on his guard. All the Duke's demonstrations could not draw his attention from his left, where the real attack was intended; but nevertheless the Duke pushed on the English and Germans under his orders, who forced the passage in the most gallant style. But when the Duke ordered the Dutch generals to support the attack of the Duke of Wirtemberg, who had crossed the river, and established himself in force on the opposite bank, they refused to move their men. The consequence was that this attack, as well planned and likely to succeed as the famous forcing of the lines a fortnight before, proved abortive; and Marlborough, burning with indignation, was obliged to recall his troops when on the high-road to victory, and when the river had been crossed, before they had sustained a loss of a hundred men. So general was the indignation at this shameful return on the part of the Dutch generals to Marlborough for all the services he had rendered to their country, that it drew forth the strongest expressions from one of his ablest, but most determined opponents, Lord Bolingbroke, who wrote to him at this juncture:--"It was very melancholy to find the malice of Slangenberg, the fears of Dopf, and the ignorance of the deputies, to mention no more, prevail so to disappoint your Grace, to their prejudice as well as ours. We hope the Dutch have agreed to what your Grace desires of them, without which the war becomes a jest to our enemies, _and can end in nothing but an ill peace, which is certain ruin to us_."[7]
