ility was low and Trollope's squadron was still using obsolete signal codes, so a number of vessels failed to comprehend Duncan's intentions, turning the advancing line into a ragged pattern of scattered vessels clustered into two loose groups. The flurry of orders was so quick and contradictory that at least one captain gave up entirely: the Scottish captain, John Inglis, of HMS Belliqueux threw his signal book to the deck in frustration and shouted "Up wi' the hel'lem and gang into the middle o't."
The combined effect of Duncan's orders was to split his fleet into two uneven divisions, each sailing in a loose formation towards the unified Dutch line. The northern, or windward, division comprised six third rate ships of the line, two fourth rate ships and the frigate Circe, tasked with repeating signals from the flagship Venerable, which led the division with HMS Triumph and Ardent close behind. This force was aiming for the Dutch flagship, Vrijheid, which lay fifth in the Dutch line. The southern, or leeward, division comprised eight third rate ships of the line and the repeater frigate HMS Beaulieu, and was led by Vice-Admiral Richard Onslow on HMS Monarch. Onslow's force was aiming for the rear of the Dutch line, to strike the fourth ship from the end. Behind the two divisions lay a line of small craft tasked with repeating Duncan's signals so that the entire fleet could see his intentions. At 11:53, Duncan raised the signal for each ship to pass through the Dutch line and attack from the far side, but the poor weather prevented the more distant ships from recognising the signal.
De Winter had originally intended to close his line up into a solid defensive platform and retreat to shallower waters while Duncan formed his own line of battle, but the sudden, disorganised British attack had thrown his plans into confusion. As a result, gaps had opened up between his van, centre and rear, leaving the last four ships greatly outnumbered and unsupported. De Winter gave urgent orders for the van and centre to drop back and assist the rear, but there was little time, and his situation looked desperate: although the Dutch and British lines each mustered 16 ships, the British vessels were almost all larger and more strongly built than their Dutch counterparts, and their crews were experienced seamen in the heavy weather conditions, while the Dutch crews, confined to port for the previous year, had little understanding of the skills required in combat at sea. The Dutch line of battle was accompanied by a second line to the east, formed from ten frigates, brigs and smaller craft. These vessels, unlike the smaller ships with the British fleet, were well armed and situated so that their guns covered the gaps between the ships that formed the Dutch line of battle, ready to rake any British vessels that attempted to break through.
Collapse of the Dutch rear guard
At 12:05, Duncan raised the signal ordering his ships to engage the enemy closely. At the same time, the Dutch ship Jupiter, under Rear-Admiral Hermanus Reijntjes, fourth from the southern end of the line, opened fire on the rapidly approaching Monarch. The Dutch ships had waited until the British were well within effective range in order to maximise the effect of their shot, and soon Onslow's flagship was under fire from the entire rearguard of the Dutch line, the ship suffering damage while attempting to break through the Dutch line between Jupiter and Haarlem at 12:30. On Monarch, Captain Edward O'Bryen remarked to Onslow that he could not see where his ship could pass between the closely formed Dutch ships, to which the Admiral responded that "the Monarch will make a passage." Striking the small gap between the ships, Onslow fired raking broadsides into both vessels and then turned to lay his ship alongside Reyntjes' flagship. As he did, the Dutch frigate Monnikkendam and the brig Daphné pulled out of the second line and attempted to fill the gap Monarch had created, firing into the British ship of the line as they did so.[Note 4] In response, Onslow opened fire on the s
