Harwich Force and destroyer professionalism

During roughly nine months of World War I service, Walker moved between the Grand Fleet and Harwich Force wherever an additional destroyer was needed. Her speed and armament suited fleet screening and inshore work. Keeping V and W destroyers with the battle fleet freed other ships for merchant-convoy escort and anti-submarine duties while retaining a torpedo force against any German fleet sortie. Alternating disciplined fleet operations with Harwich Force's aggressive small-ship work helped develop a specialist destroyer cadre. The precise movements of individual ships are difficult to reconstruct because flotilla members shifted between these assignments.
