HMS Mersey (1913)

HMS Mersey was a Humber-class monitor of the Royal Navy. Originally built by Vickers for Brazil and christened Madeira, she was purchased by the Royal Navy in 1914 on the outbreak of World War I along with her sister ships Humber and Severn.

She had a relatively successful career in World War I and had two prominent incidents. At the Battle of the Yser in 1914, off the coast of Belgium, she bombarded German troops as well as artillery positions. In July 1915 she was towed to the Rufiji River delta in German East Africa where she and Severn then assisted in the destruction of the Kaiserliche Marine cruiser Königsberg. Her log books from March 1915 to December 1917 can be viewed online at naval-history.net.

She later went to the Mediterranean and served on the River Danube. In 1921 she was sold to the breakers.
