Sugar and cocoa turn sea control into economic power

The discussion broadens from Guadeloupe to the commodity consequences of maritime control. With Caribbean routes dominated by Britain, continental Europe lost easy access to cane sugar and expanded beet-sugar production under the Continental System. British shipping also carried much of the cocoa reaching Europe while Spain and Portugal were disrupted by the Napoleonic Wars. These were not incidental luxuries: high-value colonial goods generated trade, shipping demand, customs revenue, and credit. Command of sea lanes translated island conquest into economic leverage far beyond the battlefield.
