Many of the Confederates demanded that an advance should be made upon Washington, and, had it been done promptly, it could have been captured without difficulty. Realizing its danger, the national government called upon the States for troops and several regiments were hurried thither. While the Seventh Pennsylvania and Sixth Massachusetts were passing through Baltimore, they were savagely assailed by a mob. A portion of the Sixth Massachusetts were hemmed in, and stoned and pelted with pistol-shots. They remained cool until three of their number had been killed and eight wounded, when they let fly with a volley which stretched nearly a dozen rioters on the ground, besides wounding many others. This drove the mob back, although they kept up a fusillade until the train drew out of the city with the troops aboard. ACTIVITY OF THE CONFEDERATES. The Confederates in Virginia continued active. They captured Harper's Ferry and the Norfolk Navy Yard, both of which proved very valuable to them. Their government issued "letters of marque" which permitted private persons to capture merchant vessels belonging to the United States, against which the Confederate Congress declared war. The border States were in perhaps the most trying situation of all, for, while they wished to keep out of the war, they were forced to act the part of buffer between the hostile States. The secessionists in Maryland, Kentucky, and Missouri made determined efforts to bring about the secession of those States, but the Union men were too strong. The armies on both sides received many recruits from the States named, which in some cases suffered from guerrilla fighting between former friends and neighbors. Kentucky, whose governor was a secessionist, thought she could hold a neutral position, but the majority of the citizens were Union in their sentiments. Besides, the situation of the State was such that it was soon invaded by armed forces from both sides, and some of the severest battles of the war were fought on its soil. THE WAR AS VIEWED IN EUROPE. The prospect of the splitting apart of the United States was pleasing to all the European powers, with the single exception of Russia. France was especially urgent in favoring an armed intervention in favor of the Confederacy, but England would not agree, nor would she recognize the Confederate States as an independent nation, for, had she done so, the United States would immediately have declared war against her. In May, however, England declared the Confederacy a belligerent power, thereby entitling it to make war and man war vessels, which could take refuge in foreign ports. While this recognition was of unquestionable help, it would not have amounted to a great deal had not England permitted the building of swift and powerful cruisers, which were turned over to the Confederates, and did immense damage to Northern commerce.
