I live near the River Thames in Ham with Teddington Lock very close by.
Apparently a local boat yard owner back in 1940 got 100 small boats together at Teddington Lock and they all set sail for Dunkirk.
This website has some pics of the 'Little Ships' when they got together at Teddington for the Diamond Jubilee Pageant
Dunkirk "Little Ships" return to Teddington Lock ? Teddington, Middlesex, UK
