Gallipoli showed why admirals valued Somerville's communications

Successive senior officers gave Somerville glowing wartime appraisals because he combined scientific and engineering knowledge with practical signal handling. At Gallipoli he developed methods for coordinating forces ashore, ship-to-shore movement, and supporting fleets. Those systems addressed the difficult problem of keeping an amphibious operation connected across land and sea. In this account, the arrangements fed into Royal Navy communications doctrine later used during the Second World War, including at D-Day. An operational defeat still produced institutional learning that may have saved lives in later amphibious campaigns.
