So resolved were the Dutch to have a general clearing-up with England on all points concerning the sovereignty of the sea, that they at first proposed to insert among their draft articles one relating to the striking of the flag and similar ceremonies, which frequently gave rise to differences. The States-General, however, considered the matter “too delicate” to be raised at that time, and the article was not inserted.[698] Two or three months before this, as elsewhere mentioned (p. 398), the question of striking the flag to the English had been raised and debated in the States-General in connection with Tromp’s expedition to the Scilly Islands. With the foregoing proposals before him, it is not to be wondered at that St John was dissatisfied, and longed more than ever to get away from The Hague. The Commonwealth had asked for a strict and close alliance at the very least, for the security of religious and political liberty and the common interests of both Republics, but in reality and above all for aid against the royalists. The Dutch also desired security for liberty, but it was chiefly for the liberty of commerce, navigation, and fishing; and they were anxious, if they could, to get rid of the troublesome English pretension to a sovereignty of the sea. The proposals of the two sides were incompatible, and St John left The Hague a few days later with the unuttered plan for the fusion of the nations in his pocket and with bitterness in his heart. His disappointment was to cost the Dutch dear. Within a few months of his return the Navigation Act was passed, mainly by his impulse, and it dealt a serious blow to the commerce of the United Provinces.[699] It was the retort of the English Commonwealth to the rebuff of the States. If the Dutch put their commerce and fisheries above everything else, the Parliament would show them how they could injure them and at the same time foster English shipping and fisheries.
