On May 5, 1905, the Royal Navy Drake-class armoured cruiser HMS King Alfred ran aground off Shoeburyness in Essex. The incident occurred shortly after the ship's initial commissioning during early sea trials or post-construction shakedowns in the Thames Estuary.

​

The vessel was subsequently refloated with minimal lasting damage and in 1906 went on to begin her career being deployed to the Far East. She remained in active service until she was sold for scrap in 1920.
