In the port of Nantes, the Convention’s envoy, Jean-Baptiste Carrier, also found the guillotine was too inefficient for the rate of death he required. So he tried a different method, in which 90 priests were hogtied in a holed boat in the Loire and sunk. This technique, called a ‘vertical deportation,’ became one of his primary methods. Around 1,800 people were killed in this way.
