Battle of The Downs - Losses

Losses

According to the Spanish naval historian Cesáreo Fernández Duro, of the 38 ships that attempted to break the Dutch blockade, 12 ran aground on the Downs (of which 9 were refloated and managed to reach Dunkirk), one was burnt by a Dutch fireship, 9 surrendered (of which 3 were so damaged that sank on the way to port) and 3 ran aground on the coasts of France or Flanders to avoid capture.
The French diplomat Comte d'Estrades, in a letter to Cardinal Richelieu, claimed that the Spanish had lost 13 ships burnt or sunk, 16 captured with 4,000 prisoners, and 14 lost off the coasts of France and Flanders, a figure higher than the number of Spanish ships present at the Downs. D'Estrades also reported in his letter that the Dutch had lost 10 ships sunk or burnt. This source is cited by Jean Le Clerc in his Histoire des Provinces-Unies des Pays-Bas.
The Portuguese Admiral and historian Ignacio Costa Quintella gives figures of 43 ships and 6,000 men lost by the Spanish and some ships and more than 1,000 men by the Dutch.
The Dutch sources only mention one Dutch ship lost that got entangled with the Santa Teresa and about a hundred persons dead. Historian M.G de Boer who did extensive research and published a book about the subject confirms this and puts Spanish losses in ships and men at about 40 and 7000 respectively.
