The country between Lambeque and Steinkirk was intersected by innumerable hedges and ditches; and neither army could approach the other without passing through several long and narrow defiles. Luxemburg had therefore little reason to apprehend that he should be attacked in his entrenchments; and he felt assured that he should have ample notice before any attack was made; for he had succeeded in corrupting an adventurer named Millevoix, who was chief musician and private secretary of the Elector of Bavaria. This man regularly sent to the French headquarters authentic information touching the designs of the allies. The Marshal, confident in the strength of his position and in the accuracy of his intelligence, lived in his tent as he was accustomed to live in his hotel at Paris. He was at once a valetudinarian and a voluptuary; and, in both characters, he loved his ease. He scarcely ever mounted his horse. Light conversation and cards occupied most of his hours. His table was luxurious; and, when he had sate down to supper, it was a service of danger to disturb him. Some scoffers remarked that in his military dispositions he was not guided exclusively by military reasons, that he generally contrived to entrench himself in some place where the veal and the poultry were remarkably good, and that he was always solicitous to keep open such communications with the sea as might ensure him, from September to April, a regular supply of Sandwich oysters. If there were any agreeable women in the neighbourhood of his camp, they were generally to be found at his banquets. It may easily be supposed that, under such a commander, the young princes and nobles of France vied with one another in splendour and gallantry. [310] While he was amusing himself after his wonted fashion, the confederate princes discovered that their counsels were betrayed. A peasant picked up a letter which had been dropped, and carried it to the Elector of Bavaria. It contained full proofs of the guilt of Millevoix. William conceived a hope that he might be able to take his enemies in the snare which they had laid for him. The perfidious secretary was summoned to the royal presence and taxed with his crime. A pen was put into his hand; a pistol was held to his breast; and he was commanded to write on pain of instant death. His letter, dictated by William, was conveyed to the French camp. It apprised Luxemburg that the allies meant to send out a strong foraging party on the next day. In order to protect this party from molestation, some battalions of infantry, accompanied by artillery, would march by night to occupy the defiles which lay between the armies. The Marshal read, believed and went to rest, while William urged forward the preparations for a general assault on the French lines.
