Purchased an item on eBay today from Mike Smythe. He linked me to his site.
"At the end of the Battle of Crete in May 1941, the many troops and a small group of civilians with the support of various rearguard actions walked over 70 km across Crete to the southern beach at Sphakia with the hope of being evacuated to Egypt"
In September 2018 he plans to bring this story, to you and many others, using soldiers personal accounts, original photos, maps and unit diaries as he traces the original route documenting it as he goes.
Here is a link to his site
