About this time the Prussians, having received orders to proceed to the south, separated from the British force; and Graham’s position on the frontier of Holland was far from secure. He fell back, as we have seen, from Antwerp, and occupied ground between that place and Breda. He eventually resolved to attempt the capture of Bergen-op-Zoom. The Riflemen moved on February 28 to West Wesel. In the storm of Bergen and its failure they had no part; for on March 8 (the day on which the attempt was made) they marched in the evening towards Antwerp, it being understood that their destination was to attack Fort Lillo. They marched all night, and towards morning were countermanded and halted; and some hours afterwards heard of the failure at Bergen-op-Zoom. However a picquet of the 3rd Battalion was left near Bergen; and on the failure of the attack on it, they were ordered late in the night of the 8th to retire, and to make the best of their way to their companies. This they effected; but with barely sufficient time to call in their advanced sentries.[145] On the 9th the Riflemen halted at Stabroek, and on the 11th moved to Capellen. Another sortie was made by the enemy from Antwerp on March 26, and the Riflemen were under arms expecting an attack; but none took place on them, the enemy having retired. Such alarms and affairs occasionally occurred; for on the 30th the Riflemen pursued a foraging party of the enemy, but unsuccessfully, for they made good their return into Antwerp before the Riflemen could intercept them. But all really active operations of this expedition terminated with the failure at Bergen-op-Zoom. Some further operations were contemplated; but as Graham was on the point of executing them, news reached the Riflemen on April 4 of the entrance of the Allies into Paris on March 31. However by the Treaty of Paris the Kingdom of the Netherlands was to be established; and pending the details of that measure being arranged by the Congress of Vienna, an Anglo-Hanoverian force was to remain in the country. The Rifle detachments formed part of it. Early in April a detachment of one company was sent to occupy Fort Batz, and on April 15 the Riflemen moved from Capellen to Braeschaet and Schooten; on the 29th they marched to Contich, and on the 30th to Mechlin, where they remained about a fortnight. On May 14 they arrived at Brussels; where on the 30th they were reviewed by the Prince Sovereign of the Netherlands, as he was then styled, afterwards the King of the Netherlands.
