The Dutch rearguard under Lieutenant-Admiral Cornelis Tromp set upon a starboard tack, taking the battle toward the Flemish shoals, compelling Albemarle to turn about, to prevent being outflanked by the Dutch rear and centre, culminating in a ferocious unremitting battle that raged until nightfall.

In the major battles of 1666, the Dutch navy still had to get used to its brandnew, much heavier, warships and some costly tactical mistakes had been made ; also personal conflict between Lieutenant-Admirals Michiel de Ruyter and Cornelis Tromp had damaged the unity of the fleet.

Despite disadvantageous weather conditions Monck decided to attack the Dutch rear under Lieutenant-Admiral Cornelis Tromp hoping to cripple it before the Dutch centre and van could intervene.

Many expected that Tromp's son Cornelis would now take command of the confederate fleet, especially Cornelis Tromp himself, who had already been given a temporary commission.

In this Second Anglo-Dutch War ( 1665 – 1667 ) he won a hard-fought victory in the Four Days Battle ( June 1666 ) but narrowly escaped disaster in the St James's Day Battle ( August 1666 ) which brought him into conflict with Cornelis Tromp, eventually leading to Tromp's dismissal.

He was succeeded as supreme commander by Cornelis Tromp in 1679.

The Dutch fleet of 75 ships and 30 fireships was commanded by Lieutenant-Admiral-General Michiel de Ruyter, with Lieutenant-Admirals Adriaen Banckert in charge of the van and Cornelis Tromp the rear.
