2 Sovereigns - Elizabeth II End of World War I - Dover Strait, Gold Piedfort

The Strait of Dover selection within this commemorative series references the critical naval chokepoint where the Dover Patrol operated from 1914 to 1918, mining the Channel and running continuous anti-submarine operations to prevent German U-boats from accessing the Atlantic shipping lanes. The patrol's success — denying free passage to the majority of U-boats attempting the strait — is frequently overshadowed by the larger Jutland narrative, but the Channel blockade was arguably the more consequential sustained operation of the naval war.

Gibraltar's role as issuer carries a quiet irony: another strait, another chokepoint, a different century.
