***About the Calanda ship:
A single name, a single number: Calanda, 1. ‘Calanda’ after the eponymous cargo ship built in 1913, which flew under Switzerland’s flag from 9 April 1941. ‘1’ in a nod to the Calanda having been the very first ship to be recorded on the Swiss boat register, assigned Basel as its home and registration port. This was a powerful symbol for a neutral country, which had decided to equip itself with a fleet to ensure supplies could reach it by sea in light of the German and Italian troops encroaching on Greece. After many services given, the ship finally retired and was dismantled in Hong Kong in 1953.
