Fowle's New Hampshire Gazette And General Advertiser

A correspondent has favored us with the following extract of a letter from the Hague, [Holland] dated September 21.

"If we may judge of events by the dispositions that announce them, we can no longer doubt that war must begin immediately; the Austrians are almost at the gates of Lillo, to the number of 8 or 9000 men, under the command of the Governor-General himself: another army is encamped near Tongres, under the command of the Generals Colloredo and Alton, and a third division of the same force is at Hoggstraten, near Breda.

The troops that are in full march from Germany, are to encamp, as they arrive, on the borders of the Meuse, near Maestricht. To face every danger, and shew, at least, that to yield benevolently is not their intention, the States-General have given orders to begin the inundations at Lillo, at Sas de Gand, and all the circumjacent Polders (Dykes): This has already made some advanced guards of the Austrians to fall back, who had made a lodgment at Putten, closed by Lillo.

At Breda, his Serene Highness the Prince Stadtholder, has erected strong batteries in all the places that are accessible, and inundated all the rest. At Bois le Duc, the Count de Maillebois, who has assembled his legion there, has taken the same precautions, to secure the town from an insult. In Dutch Flanders, General Dumolin is exerting, with the genius and activity peculiar to himself, every means that art and nature can furnish for the defence of that favored country; and as to Maestricht, that city is so well garrisoned that an army of forty thousand men would certainly miscarry against its walls.

We may then assure, without fear, that the Emperor ought to have at least twice as many troops as he has, to hope to break in upon the Republic, whose whole System is purely defensive, and consists in waiting for the enemy, shut up within her own ramparts, But the state of the question is to know, whether things will really come to this extremity; and those who can have the best information always incline to, and bet for, the negative. And, indeed, two couriers are arrived, one upon another, at the Ambassador of France's hotel, who immediately had long conferences with the Ministers of State; and it has transpired in public, that the Court of Versailles, which nothing suits worse than this war, demands even with instance, that the Republic will terminate amicably with the Emperor; and as a courier has been dispatched this morning, it is concluded from it, with some likelihood, that he is charged with pacific proposals. This is an exact account of the present state of things."

M. de Maillebois is decidedly appointed General in Chief of all the troops of the State (under the Captain General.)

The Generals Sandez, Verschuur, and Kretschmaur, set out from hence this morning for Breda.
