The High Seas Fleet ran into Jellicoe's battle line, turned away twice, and fought through the night to escape. The Harwich Force should have been ordered north as soon as the scale of the engagement became clear. Its destroyers and light cruisers might have blocked or slowed a German turn south, buying the Grand Fleet time to renew contact. Holding that force back because the Grand Fleet already seemed sufficient was a strategic failure in London rather than a criticism of Jellicoe's tactical deployment.
