Not everyone will know about this totally obscure and ultimately pointless campaign of 27 August to 19 November 1799 during the War of the Second Coalition, in which an expeditionary force of around 30,000 British and Russian troops invaded the North Holland peninsular in the Batavian Republic.
The campaign had two strategic objectives: to neutralise the Batavian fleet and to promote an uprising by followers of the former stadholder William V against the Batavian government. The British sought assistance from Russia’s Czar Paul who agreed, probably/certainly influenced by a fair bit of cash, to send a corps to join the British in this venture. True to form the British didn’t really have a plan, and according to Fortesque, didn’t even know, or couldn’t agree, where to invade, beyond the general objective of ‘The Netherlands'. They eventually chose to land on the windswept low lying North Holland peninsular. It was a good choice as it was close to the Dutch navy’s anchorage. It was a bad choice as the land was flat, criss-crossed with dykes, was inundated with standing water, (and where it wasn't, was extremely sandy with high dunes,) had few roads, and invaders could be easily contained and prevented from moving south towards Amsterdam.
