A Letter came yesterday to a Member of the Honourable House of Commons , by the way of Scotland , relating to the Affairs of Londonderry , being sent directly from that Town by an Advice-Boat to Kintire , which gives such a satisfactory Account of the great and glorious Success the Protestants of Derry , Bellishanon , and Iniskilling , have obtained over the Irish Army , that they have now caused them intirely to Raise the Siege , whereby they are now full Masters of the Field for 20 Miles in Circuit : Those of Derry having on the 2d of this Instant June made such a successful Sally with about 5000 Men , that in less than two hours they drove them from their Post , and had the persuit of them for Three Miles in length , having , as it is modestly computed , killed above 1500 upon the Spot , and have seized all their Cannon , Baggage , and Ammunition , being Two Brass Culverings for Battery , Five Field-Pieces , and Two Mortars . And had some days before , by the assistance of a Vessel which brought them Meal out of Scotland , attacked and became Masters of Kilmore Fort , some 3 Miles distant in the Lough from the City . And adds , That so soon as they shall have Assistance from England , especially some Troops of Horse , they will make further progress into the Country , and already have advanced above Ten Miles , and brought into the Town a considerable Supply of Provision .

The Prisoners inform , That the late King James design'd , if the Protestants had not drove them off , to call them from before it , in order to make Three Encampments , upon the Advice received from England , of the Intention of Duke Schombergh to be in person among them , who they very much dread , even the French Bravadoes themselves ; and add , That whenever he arrives , he will be doubly increased in Number as well by some of the Irish , who begin to be weary of the French Yoke , and think thereby to save their Estates , as by the Protestants themselves .

The same Letters say , That Colonel Kirk was the 5th Instant in Ramsey Bay in the Isle of Man , having several times attempted to Sail forwards , but impeded by contrary Winds . But on the Friday following , the Wind being N. W. and by W. He , with all his Fleet , being 24 in Number , set Sail , and was out of sight , and 't is not to be doubted but he is arrived there before this , whose coming is impatiently expected . And we hear that Capt Pettwell in the Jerusalem , with two other Ships in his Company , sailed some time before from Bristol , with intent to get into Derry , and 't is verily believed that they have been some time since arrived , and were those Vessels that assisted in reducing the Fort of Kilmore .
