The 1st Isle of Wight Rifle Volunteers, later the 8th Battalion, Hampshire Regiment, but known informally as the 'Isle of Wight Rifles', was an auxiliary unit of the British Army formed to defend the Isle of Wight after a mid-19th Century invasion scare. During World War I it fought in the Gallipoli Campaign, taking part in the calamitous attack at Suvla Bay, and later at the battles of Gaza and Megiddo in Palestine. Between the wars it was converted to coast defence artillery and served in this role on the Isle of Wight throughout World War II. One battery was sent to reinforce the garrison of Tobruk, where it was captured in 1942. Postwar the unit converted to the air defence role, then reverted to infantry, and its successors continue in today's Army Reserve.

Prince Henry of Battenberg, formerly Count Henry of Battenberg, was a morganatic descendant of the Grand Ducal House of Hesse. He became a member of the British royal family by marriage to Princess Beatrice of the United Kingdom, the youngest child of Queen Victoria. Through his daughter, Victoria Eugenie, who became the queen consort of Spain, Henry is a direct ancestor of the current Spanish royal family.
