The matter then dropped, and the Duke was present at the conference on the morrow. Finally, Austria and England bound themselves to make great efforts, the latter with at least 40,000 men, either British or German auxiliaries. The Prussian and Dutch forces were to be increased so as to bring the grand total to 340,000 men. Of this large number 170,000 were to operate in Flanders with a view to a march on Paris; 35,000 held the country along the right bank of the Meuse; 15,000 protected Luxemburg; 65,000 Prussians prolonged the line eastwards to the Rhine, which was guarded by 55,000 Austrians. Certainly the plan called for a third of a million of men, if all the frontier strongholds of Flanders were to be taken before the march to Paris began. In regard to details, Pitt, Grenville, and Dundas urged that Cornwallis should command the British and subsidiary forces defending West Flanders--a suggestion which George III warmly approved, on condition that the Duke of York, serving with the main body nearer the centre of the long line, had a number of troops proportionate to his rank and talents. Thus the effort of Pitt and his colleagues to shelve the Duke of York was foiled. On another and weightier matter he had his way. Coburg's conduct had been so languid and unenterprising as to lead to urgent demands for his recall; and it was understood that the Emperor Francis would take the command, with Mack as Chief-of-Staff and virtual director of the campaign. Pitt expressed to Mack his marked preference of this arrangement to the alternative scheme, the appointment of the Archduke Charles; for the extreme youth of the Archduke might hinder a good understanding between him and his subordinate and senior, the Duke of York. Seeing, then, that Mack declined absolutely to serve under Coburg,[346] nothing but the presence of the Emperor could end the friction in Flanders.
