Indivisible". The new régime abolished cantonal sovereignty and feudal rights. The occupying forces established a centralized state based on the ideas of the French Revolution. Ostend Raid On 18 May the British launched a combined Royal Navy and British Army raid on Ostend to destroy the lock gates of the Bruge Canal and to burn the French gun-ships that were in the harbor. The objectives were achieved but the entire army contingent of 1,300 men was either killed or captured. Ireland An expeditionary force was sent to County Mayo in Ireland to assist in the rebellion against Britain in the summer of 1798. On 22 August, nearly two months after the main uprisings had been defeated, about 1,000 French soldiers under General Humbert landed in the north-west of the country, at Kilcummin in County Mayo. Joined by up to 5,000 local rebels, they inflicted a humiliating defeat (known as the Castlebar races to commemorate the speed of the British retreat) on the British at the Battle of Castlebar and set up a short-lived "Republic of Connacht", before final defeat at the Battle of Ballinamuck, in County Longford, on 8 September 1798. Second Coalition By the end of the year, the European powers, having recovered from their previous defeats and emboldened by Napoleon's absence, organized a new Second Coalition. The only military activity before the end of the year was in Italy, where Naples captured Rome on 28 October but was driven out by the end of the year.
