The Brandenburg squadron, mistakenly believing to have encountered a
Spanish convoy of merchant ships returning fully laden with precious metals, spices, and luxuries from the Americas, attacked the far superior Spanish warship squadron that had been sent out in search of the suspected raiders, but retreated into the safety of the Portuguese port of
Lagos when their mistake became clear. While the Branderburgers repaired their damage in Lagos, the Spanish merchant convoy safely slipped into
Cádiz. ==Ships involved==
