I want to know the answer to the following question:
What act gave control of Saint Helena to the British Crown?
All the background I'm provided with is that "The latter half of the 19th century saw the advent of steam ships not reliant on trade winds, as well as the diversion of Far East trade away from the traditional South Atlantic shipping lanes to a route via the Red Sea (which, prior to the building of the Suez Canal, involved a short overland section).". Is that enough to answer the question?
Answer: no
