Chart of the fleets in the battle of Trafalgar

On 16 September, Napoleon gave orders for the French and Spanish ships at Cádiz to put to sea at the first favourable opportunity, join with seven Spanish ships-of-the-line then at Cartagena, go to Naples and land the soldiers they carried to reinforce his troops there, then fight decisively if they met a numerically inferior British fleet.
