sentences:  At this time Millbay was the only harbour of Plymouth that was out of reach of the Royalist artillery so it became the sole source of resupply for the town.From the end of the Civil War Millbay reverted to a quiet anchorage with no jetties or port facilities, but in 1756 John Smeaton built a jetty and workyard in the south west corner of the harbour for unloading and working the stone for the third Eddystone Lighthouse.A ten-ton ship, named the "Eddystone Boat", was based here and took the worked stones out to the reef.
