An engagement between Spanish and Dutch ships, with a small yacht on the far left flying the States General flag. Next to it is a Dutch ship in starboard-bow view, flying the Dutch flag from the foremast and the mizzen mast. A number of figures can be seen on deck; a man in the stern blows a trumpet to sound the action and a figure next to him stands brandishing a sword. She is engaged in gunfire with the larger ship, half-visible behind in port-quarter view, which is flying an unidentified flag, probably Spanish, at the stern. This ship bears a crest containing a figure carved on the stern and also a flag depicting Christ, or John the Baptist, from the mizzen mast. To the right of centre is a Dutch flagship in starboard and stern view. She bears the arms of Haarlem on her stern which may indicate the name and identity of the ship as the 'Haarlem'. This opponent is the smaller ship in the foreground on the far right, in broad port-bow view. She flies a flag on the stern with a red diagonal cross on a white background and also showing a figure of Christ. This is probably an ensign of the Spanish Netherlands. She also flies a white saltire cross on blue at the foremast. Wreckage can be seen in the foreground including two flags to indicate a ship in the central position that has sunk.
