This hollow on Fleet Brook gives a good idea of why it was so difficult for the liberators to roll up this part of the Ruhr Triangle. The many streams running from east to west, which flooded quickly in wet weather, made the low-lying terrain soggy, making mechanical warfare with tanks impossible and commandos were deployed.
