Of these, twenty-three thousand were British, the most important force that England had sent to the Continent since the days of King Henry the Eighth. The organisation was remarkably like that of the New Model. William was, of course, commander-in-chief, and under him a general of horse and a general of foot, with a due allowance of lieutenant-generals, major-generals, and brigadiers. There is, however, no sign of an officer in command of artillery or engineers, nor any of a commissary in charge of the transport.[262] The one strangely conspicuous functionary is the Secretary-at-War, who in this and the following campaigns for the last time accompanied the Commander-in-Chief on active service. But the most significant feature in the list of the staff is the omission of the name of Marlborough. Originally included among the generals for Flanders, he had been struck off the roll, and dismissed from all public employment, in disgrace, before the opening of the campaign. Though this dismissal did not want justification, it was perhaps of all William's blunders the greatest.

They had already broken the line of the defending fortresses by the capture of Mons; they now designed to make the breach still wider. All through the winter a vast siege-train was collecting on the Scheldt and Meuse, with Vauban, first of living engineers, in charge of it. In May all was ready. Marshal Joyeuse, with one corps, was on the Moselle, as in the previous year, to hold the Brandenburgers in check. Boufflers, with eighteen thousand men, lay on the right bank of the Meuse, near Dinant; Luxemburg, with one hundred and fifteen thousand more, stood in rear of the river Haine. On the 20th of May, King Lewis in person reviewed the grand army; on the 23rd it marched for Namur; and on the 26th it had wound itself round two sides of the town, while Boufflers, moving up from Dinant, completed the circuit on the third side. Thus Namur was completely invested; unless William could save it, the line of the Sambre and one of the most important fortresses on the Meuse were lost to the Allies.
