query: Was Operation Hush successful?
passage: Operation Hush
The Germans used mustard gas for the first time, supported by a mass of heavy artillery, which captured part of the bridgehead over the Yser and annihilated two British battalions. After several postponements, Operation Hush was cancelled on 14 October 1917, as the advance during the Third Battle of Ypres did not meet the objectives required to begin the attack. In April 1918, the Dover Patrol raided Zeebrugge, to sink block ships in the canal entrance to trap U-Boats, which closed the canal for a short time. From September–October 1918, the Belgian coast was occupied by the Allies, in the Fifth Battle of Ypres.
