There was still a short interval before the commencement of military operations. William passed that interval in his beloved park at Loo. Marlborough spent two or three days there, and was then despatched to Flanders with orders to collect all the English forces, to form a camp in the neighbourhood of Brussels, and to have every thing in readiness for the King's arrival. And now Marlborough had an opportunity of proving the sincerity of those professions by which he had obtained from a heart, well described by himself as harder than a marble chimneypiece, the pardon of an offence such as might have moved even a gentle nature to deadly resentment. He received from Saint Germains a message claiming the instant performance of his promise to desert at the head of his troops. He was told that this was the greatest service which he could render to the Crown. His word was pledged; and the gracious master who had forgiven all past errors confidently expected that it would be redeemed. The hypocrite evaded the demand with characteristic dexterity. In the most respectful and affectionate language he excused himself for not immediately obeying the royal commands. The promise which he was required to fulfil had not been quite correctly understood. There had been some misapprehension on the part of the messengers. To carry over a regiment or two would do more harm than good. To carry over a whole army was a business which would require much time and management. [66] While James was murmuring over these apologies, and wishing that he had not been quite so placable, William arrived at the head quarters of the allied forces, and took the chief command.
