After we landed, we had
a new driver and a new bus. Pat took a few photos at the harbour and a
pit stop before our first glimpse of a Churchill Barrier. Britain
realized during WWI that its naval base at the mainland of the Orkneys
needed protection, and enemy ships began to be sunk on the eastern
side of the deepest channels leading to the Scapa Flow. At the end of
WWI, the entire German fleet was brought there and the captains
scuttled their own ships rather than turn them over.
