This action was a preliminary to the battle of the downs which took place on 21 october. This view is taken from the english coast, with deal in the left foreground, deal castle in the centre, sandown castle to the right with the cliffs of dover beyond. Both boll and hollar were in england at the time of this event and one or both may have witnessed the action. The spanish fleet had intended to anchor in the roadstead of the downs under cover of english neutrality, in order to ferry supplies for the spanish army in the netherlands across the channel to dunkirk. On the 15 september, the large spanish fleet was seen coming up the english channel by a smaller dutch naval force and a short skirmish took place. This was followed, three days later, by the action of 18 september, shown in this view, in which the 29 ships of the dutch fleet were pitted against the 67 ships of the spanish. The action lasted over a couple of days until the dutch ran out of gunpowder and the spanish retreated to the roadstead of the downs.
