Operation Hush was a British plan to make amphibious landings on the Belgian coast in 1917 during World War I, supported by an attack from Nieuport and the Yser bridgehead, which were a legacy of the Battle of the Yser (1914). Several plans were considered in 1915 and 1916, then shelved due to operations elsewhere. Operation Hush was intended to begin when the main offensive at Ypres had advanced to Roulers and Thourout, linked by advances by the French and Belgian armies in between.
