In December 1793, Hoche was arrested, probably owing to his colleague's denunciations, and Pichegru became
commander-in-chief of the
Army of the Rhine and Moselle. He was summoned to succeed Jourdan in the
Army of the North in February 1794, subsequently fighting
three major campaigns within the year. The forces of the
Kingdom of Great Britain, the
Dutch Republic and
Habsburg Austria held a strong position along the
Sambre to the
North Sea. After attempting to break the Austrian centre, Pichegru suddenly turned their left, and defeated the
Count of Clerfayt at
Cassel,
Menin and
Courtrai, while his subordinate,
Joseph Souham, defeated
Prince Josias of Coburg in the
battle of Tourcoing in May 1794. After a lull, during which Pichegru feigned a
siege of Ypres, he again attacked Clerfayt, and defeated him at
Roeselare and
Hooglede, while Jourdan, commanding the newly named
Army of Sambre-et-Meuse, withstood Austrian attacks in the
battle of Fleurus (27 June 1794), which eventually led to Allied evacuation of the
Low Countries. Pichegru began his second campaign by crossing the
Meuse on 18 October, and, after taking
Nijmegen, drove the Austrians beyond the Rhine. The Anglo-Hanoverian army withdrew behind the
Waal. Then, while Pichegru's troops prepared to go into winter quarters, the
Convention ordered the Army of the North to mount a winter campaign. On 27 December two brigades crossed the Meuse on the ice, and stormed the
Bommelerwaard. On 10 January Pichegru's army crossed the ice of the Waal between
Zaltbommel and
Nijmegen, then, on 13 January, entered
Utrecht, which surrendered on the 16th. The Anglo-Hanoverian army retreated behind the
IJssel and then withdrew to
Hanover and
Bremen. Pichegru, who had successfully penetrated the frozen
Hollandic Water Line, arrived in
Amsterdam on 20 January, after the
Batavian Revolution had taken place. The French occupied the rest of the
Dutch Republic in the next month. This major victory was marked by unique episodes, such as the
Capture of the Dutch fleet at Den Helder by French
hussars, and exceptional discipline of the French battalions in Amsterdam, who, although faced with the opportunity of plundering the richest city in Europe, showed self-restraint. ==Thermidor and Directory==
