After returning to the United Kingdom in 1904, "Victorious" served as the second flagship of the Channel Fleet. She remained in active service with the fleet in various units until 1908, when she was modernized and then placed in reserve. At the outbreak of the First World War in August 1914 she was mobilized with three of her sister ships into the 9th Battle Squadron, though by January 1915 she was again withdrawn from front-line service. In September her main guns were removed to arm a pair of monitors. "Victorious" was subsequently used as a repair ship. After the end of the war she was renamed "Indus II"; plans to use her as a harbor ship were cancelled and, in April 1923, she was sold for scrap.
