Hague, 4th of June. "M. de Nowicoff, Secretary of the Prince de Gallitzin, Envoy Extraordinary of the Empress of Russia, being returned here the first of this month at night, from Petersburg, where he has been as express some weeks ago, the Prince de Gallitzin had the next day a conference with some members of government. A second express, sent to Petersburg by the same Minister about the middle of April, returned last night. We flatter ourselves, that the despatches which they bring will contribute to accelerate the execution of the project of an armed neutrality, for which her Imperial Majesty continues to testify the most favorable dispositions, provided that the other neutral powers act readily in concert with her. The merchants of Dort and Rotterdam have followed the example of those of Amsterdam, by presenting on the 2d a petition to the States-General, to the end to supplicate them to hasten the equipment of the vessels, which it has been resolved to arm, and to give to commerce the effectual enjoyment of the protection of the State. According to the ordinance projected to accelerate this equipment, 'no merchant vessel belonging to the subjects of the Republic can put to sea, without voluntarily delivering to the college of the Admiralty at least the third man of her crew, under penalty of six hundred florins per head, upon the captains and freighters of the vessel, which shall attempt to go out without having made the said delivery.' It will not, however, take place but twice a year, viz. the two first voyages which a vessel shall make, and from this will be excepted those upon which there shall be but two men besides the master, the vessels employed in the different fisheries, the ships of the East India Company, and those of the West Indies; in fine, the foreign vessels manned with crews of their own nation, &c."

April 21st, 1780. "It happened that the French privateer, the Spring, commanded by Captain John Huë, and mounted with four guns, which had anchored in the Road of Helvoetsluys, put to sea in company with some Dutch vessels, bound to the Greenland Fishery. Three Scotch coal vessels put to sea at the same time, and soon after two others, somewhat larger. The three largest having come just opposite the point of Westland, the French privateer, which was not at the distance of more than four yards from the shore, opposite the Cape of the Isle of Goree, wore round to return into port; the three coal vessels perceiving it, made the same manœuvre, and bore down upon the French privateer, upon which the latter approaching nearer and nearer the coast, and passing along very near it under the city of Goree, to enter into the port, they began to fire upon him with ball, and they continued to cannonade him incessantly, although this little vessel, which in truth carried French colors, did not answer them with more than one gun. They pursued him quite up to the lighthouse of Goree, only at the distance of about six yards (I suppose ship's yards) west of the place, where they forced her to run ashore. The vessel was there stopped upon the sand, and the crew crawling along upon the bowsprit in the sea, saved themselves at land. Meantime, the three coalmen did not cease to fire upon the little privateer, without regarding even a large number of workmen who were about their business on shore. So that the bullets passed through the midst of these people, and just over their heads, and they were very happy to run off and save themselves in the Downs. The three coalmen, not content to have pushed thus far their enterprise, continued not only to fire upon the privateer stopped in the sand, without any crew, but in fine, they came to anchor at the distance of about forty yards from this vessel, while the two smaller coalmen were come out of the Bay of Helvoetsluys, and were under sail near and round it, firing upon it until noon, when the tide began to set afloat the privateer, which had been stopped for two hours. Then the English went on board with their boats, took down the French flag, took the vessel off the shore, and attached her broadside and broadside to the largest of the coalmen. They took away from her many effects, under the eyes of the Dutch coasting pilots, who having asked in English, what was their design in regard to the privateer, and having cautioned them to take care what they did, the captain of the largest of the coalmen answered, "We will take her, we are also privateers."

Their Noble and Grand Mightinesses, the States of Holland and West Friesland, after having stated these circumstances to the States-General, have adopted in their report; "that they considered this excessive audacity of the English or Scotch coalmen, as a manifest and voluntary violation of the territory of the Republic, accompanied with circumstances the most aggravated, as having been committed in going out of a harbor of this country, and in a place where it could not be doubtful that they were within reach of the cannon of the shore, since their own balls reached the land, without the least provocation from the French privateer, which did not fire a single gun. So that this action of the coalmen, has had no other cause than a premeditated hostility, whilst there was not the least reason to fear that the privateer, after having got to sea, would interrupt one of them, considering that the attack was begun on their part, in the very moment when the privateer had tacked about to quit the open sea and return into port, besides, that he was pursued for two hours after that he was indubitably aground upon the shore, and that the enterprise was finished by taking away the French privateer from the Dutch shore, contrary to the exhortation and warnings of the coasting pilots. That in the judgment of their Noble and Grand Mightinesses, the States-General had not only a right to complain of the insolence so excessive on the part of the English or Scotch masters, which their High Mightinesses admit into the ports of the Republic, but that they cannot even suffer them without wounding the neutrality, which they have embraced in the present troubles, and without prejudicing the dignity, the sovereignty, and the independence of the State; and having been under obligation effectually to have opposed and hindered them, even by force, if they could have been informed in time of these violences, they cannot excuse themselves from demanding, in a manner the most serious, the vessel which was taken, and from demanding of his Britannic Majesty, a suitable satisfaction for this conduct of his subjects."

After this report, the States-General have resolved, the 13th of May, "that advice of these facts should be sent to the Count de Welderen, Envoy Extraordinary and Plenipotentiary of their High Mightinesses at the British Court, by sending him copies of the depositions joined to the letter of the Receiver-General of the Customs of their Noble and Grand Mightinesses, in the country of Voorne, dated the 4th day of May last, by which he has informed of the facts the Lords, the Deputy Counsellors of Holland, as the said depositions are annexed to the letter, which the said counsellors have addressed to their Noble and Grand Mightinesses the 5th of the same month, concerning this affair; and at the same time, the Count de Welderen should be instructed to give notice, in the manner that he shall judge the most convenient and the most effectual, of the said insolences committed by the masters of the English or Scotch coal vessels, and to complain, in the name of their High Mightinesses, of a violation so incontestible of their territory and of the law of nations, by the way of open force; that their High Mightinesses cannot think, that his Britannic Majesty can or will suffer that his subjects should allow themselves in such excesses; that in consequence, the Count de Welderen should demand a suitable satisfaction; that the masters of the coal vessels should undergo a correction, and that the French vessel taken should be brought back to the place from whence she has been taken, or at least, that she should be restored to their High Mightinesses, to the end that they may dispose of her in the manner they shall judge proper; and that the damages caused to this vessel, directly upon the territory of their High Mightinesses, where she ought to have enjoyed the same safety as the coal vessels in the Road of Helvoetsluys, and through all the extent of the territory of their High Mightinesses, should be made good."

The English frigate, the Ambuscade, Captain Phipps, has taken, on the 24th of April last, in the Bay of Biscay, four Dutch ships, which have made some resistance, so that there were some men killed and wounded on both sides. One of the Dutch captains was killed. They were bound, it is said, from Helvoetsluys to Spain. They have been carried into Plymouth, where arrived at the same time a Spanish frigate of thirty guns, taken, they say, by the English frigate, the Medea, off the port of Brest, where she was going with despatches from the Court of Madrid, relative to the junction of the French and Spanish fleets. This is not likely, since the despatches go by land from Court to Court.

I shall finish this tedious letter, by enclosing a letter from the Count d'Urre Molans, proposing to raise some horse at the expense of himself and his officers. I promised to enclose it to Congress, which was all I could do. But I hope, before an answer can come, the American States will have no more occasion for cavalry.

I have the honor to be, &c.

JOHN ADAMS.
