During this first pass, the "Great Charity" (originally an Amsterdam Directors' ship the "Groote Liefde", which was captured during the Battle of Portland in 1653) became isolated to the east of the Dutch line and was boarded and captured by captain Jan den Haen, the later admiral, who immediately returned with his prize to the Netherlands. This obviously unsound practice would be prohibited in the Dutch fleet after this battle. Another English ship, the merchantman "John & Abigail" was also isolated, but eventually managed to rejoin the English fleet. Later an English victory tune "The Dutch Armado A Meer Bravado" declared: "Fortune was pleasant when she lent the Dutch our 'Charity' a thing they wanted much." After this, there was a second pass that needed each fleet to reverse course. Penn had inserted a new article in the fleet's Fighting Instructions requiring it to tack from the rear, so reversing the order of the fleet, but Penn later recounted that displaying the signal for this manoeuvre was delayed until after the Dutch fleet had already started to turn. Prince Rupert in the van, realising there was a problem, ordered his Red Squadron to reverse course while maintaining the same order, although his leading division under Myngs at first missed Rupert's signal. Penn then cancelled his first order and the Duke led the centre and rear of his squadron to the northwest, but his leading division under Lawson ignored his admiral's turn until the Blue Squadron under Sandwich began its own turn. This left a large gap to the rear of Rupert's White Squadron. Fortunately for the English, the Dutch fleet was sufficiently far to the north to be unable to take immediate advantage of this gap and, from 6am to 7am, the two fleets were not engaged.
