Other interesting facts that should be noted: the two most successful Confederate raiders were the CSS Alabama with 64 victims either captured or destroyed, and the CSS Florida, with 38 destroyed. Both were built in Liverpool, in direct defiance of Britain's Foreign Enlistment Act, which forbade the construction AND arming of warships in British territory for a belligerent power. While Liverpool did produce several blockade runners for the Confederacy, the US blocked any further efforts to build raiders after the Alabama. Good thing too. Between them, in the course of 2 years of operations, the Florida and the Alabama diverted numerous Union ships from blockade duties to chase them, drove insurance rates for Union shipments to astronomical heights, forced shipping vessels to either remain in port or convert to foreign registry, and are almost totally to blame for toppling the US Merchant Marine from its former position of power, which it would never regain. They sank or captured over 100 Union vessels.
