Hello again. Just finished Sword Song and as ever you never disappoint. I was particularly intrigued by the descriptions of the estuary coast around Benfleet and Canvey. Being local to both in Pitsea. I know the coastline was different then (I think the Dutch drained a lot more of Canvey in the 17th/18th centuries) I wondered if you worked from memory (You were fairly local yourself in your youth) and adjusted water levels or were there maps you found? Regards Nigel
