'Boothby' was a British naval diversion plan in support of 'Baytown' (i) (3 September 1943).

Using some of the naval force earmarked for the support of 'Baytown' (i), the undertaking was designed to persuade the Germans that the British landing was to be made not at Reggio di Calabria, across the Strait of Messina from Messina, but somewhat farther to the east at Crotone on the 'ball' of the Italian peninsula’s 'foot'.
