British troops had been forced to withdraw from France in 1940 and Greece in 1941.
If they were to return to mainland Europe to confront the Axis armies, they would have to fight their way ashore. This required huge numbers of landing craft to carry the men and supplies to the beaches.
While the major dockyards were needed for building the bigger warships, many small yards in Britain were used for the construction of landing craft of various types.
One of these was the D. Badcock (Marine) Ltd Yard (formerly the London Yard) at Cubitt Town on the Isle of Dogs.
Badcock built four large LCTs (Tank Landing Craft). As they could carry several tanks, they played an important part in amphibious operations alongside the smaller LCAs (Assault Landing Craft) and other vessels.
