This day at noon, three guerrillas were discovered in the town of Hunneville, on the Hannibal and St. Joseph Railroad, forty miles west of Hannibal, Mo. A dozen of the citizens, some armed, mustered to capture them. They had been purchasing stores, and were then at the saloon of a Union citizen, Mr. Dieman. On the approach of the squad, the guerrillas drew in defence, closed doors, and fired upon the citizens, wounding a militia captain, but not dangerously. They also fired upon Dieman, inflicting a severe wound. The citizens fired, killing two of the guerrillas, and wounding the third, who succeeded in escaping from the house and the vicinity.--the Maryland State Fair, for the benefit of the Sanitary and Christian Commissions, was opened with appropriate ceremonies at Baltimore. A speech was made by President Lincoln, in which he referred to the changes that had taken place in Baltimore during the past three years, and to the Fort Pillow massacre, which he said should be amply retaliated.--the rebel schooner Good Hope was captured and destroyed at sea, by the  schooner Fox, tender to the National steamer San Jacinto.--the rebel schooner Oramoneta, with a cargo of munitions of war, was captured off St. Augustine, Fla., by the Beauregard.
