Jean Nicolas Houchard, the next officer appointed to command, had been a heavy cavalry trooper in the Seven Years' War. His face bore the scars of wounds received at Minden, and his bravery, his stature, his bold and fierce manner, his want of education, seemed to all to betoken the ideal sans-culotte general. But he was nevertheless incapable of leading an army, and knowing this, carefully conformed to the advice of his staff officers Berthelmy and Gay-Vernon, the latter of whom, an exceptionally capable officer, had been Custine's chief of staff and was consequently under suspicion. At one moment, indeed, operations had to be suspended altogether because his papers were seized by the civil authorities, and amongst them were all the confidential memoranda and maps required for the business of headquarters. It was the darkest hour. The Vendeans, the people of Lyons, Marseilles and Toulon, were in open and hitherto successful revolt. Valenciennes had fallen and Coburg's hussar parties pressed forward into the Somme valley. Again the Allies had the decision of the war in their own hands. Coburg, indeed, was still afraid, on Marie Antoinette's account, of forcing the Republicans to extremities, and on military grounds too he thought an advance on Paris hazardous. But, hazardous or not, it would have been attempted but for the English. The duke of York had definite orders from his government to capture Dunkirk--at present a nest of corsairs which interfered with the Channel trade, and in the future, it was hoped, a second Gibraltar--and after the fall of Valenciennes and the capture of Caesar's Camp the English and Hanoverians marched away, via Tournai and Ypres, to besiege the coast fortress. Thereupon the king of Prussia in turn called off his contingent for operations on the middle Rhine. Holland, too, though she maintained her contingent in face of Lille (where it covered Flanders), was not disposed to send it to join the imperialists in an adventure in the heart of France. Coburg, therefore, was brought to a complete standstill, and the scene of the decision was shifted to the district between Lille and the coast. Dunkirk.
