during and after the First Anglo-Dutch War, including several comparable to the all but the largest English ships to augment the existing fleet, not all of these were completed or fitted out by 1665. To complete Oddam's fleet, eighteen older warships that had been laid up after the First Anglo-Dutch War were reactivated, and several very large Dutch East India Company built hybrid ships were added. These could be used for carrying cargo, as convoy escorts or in battle, although they were not as strongly built as pure warships. Perhaps realising that his fleet was still too inferior in organisation, training, discipline and firepower to challenge the English successfully in a decisive battle, Obdam prepared to postpone the fight until the wind turned favourable in order to seek a limited confrontation, with his fleet in a defensive leeward position from which it could disengage quickly and return to its ports without openly disobeying orders. However, this opportunistic attitude and lack of a clear strategic plan was a significant cause of his defeat and death. The instructions issued by the commission headed by de Witt insisted on specifying that the Dutch fleet's order of battle should involve its division into a seven squadrons with a total of 21 flag officers for political reasons. Each of the five Dutch admiralties had its own set of flag officers, including many recently appointed ones. Each of the three smaller admiralties insisted on having its own squadron, so the larger Admiralties of Amsterdam and the Maas (i.e. Rotterdam) then split their forces in two squadrons, each of similar size to those of the smaller admiralties. This resulted in seven squadrons, each with three flag officers; several were led by Lieutenant Admirals of equal rank to Obdam, who commanded his own squadron as well as the whole fleet. As the seven squadrons were not subdivided, the 14 subordinate flag officers had no clear function, except as potential replacements for their leaders. In addition, several squadrons had ships or flag officers from more than one admiralty, complicating their chain of command. Both national fleets could only be made as large as they were by employing armed merchants: the English used 24 of these, the Dutch twelve. On 11 June, a ship detached from the English fleet sighted the Dutch fleet sailing from the east with a light following breeze, and the fleet tried to close in on
