In the Civil War the youngest general in both the Union and the Confederate forces was Major-General Galusha Pennypacker, who still lives in Philadelphia. He became a captain and major at seventeen, a colonel at twenty and a full brigadier-general a few months before he became twenty-one. His last and greatest fight was at Fort Fisher and the story of that day, of which he was the hero, is typical of the bravery and readiness which made him the only boy-general in the world. By the end of 1864 the Union forces had captured one by one the great naval ports of the Confederacy, the gates through which their armies were fed by the blockade-runners of Europe. New Orleans, Mobile and Savannah had at last fallen. By December, 1864, Wilmington, South Carolina, was the only port left through which the Confederacy could receive provisions from outside. In that month an expedition was sent against the city by sea and land. The river-forces were commanded by Admiral Porter while Generals Ben Butler and Witzel had charge of the land-forces. General Butler conceived the fantastic idea of exploding an old vessel filled with powder close to the ramparts. In the confusion which he thought would result, he hoped to carry the place by assault. Fort Fisher was the strongest fortress of the Confederacy. Admiral Porter afterward said that it was stronger than the famous Russian fortress Malakoff, which next to Gibraltar was supposed to be the most impregnable fortification in the world. Fort Fisher consisted of a system of bomb-proof traverses surrounded by great ramparts of heavy timbers covered with sand and banked with turf, the largest earthworks in the whole South and which were proof against the heaviest artillery of that day. The powder-boat was an abandoned vessel which was loaded to the gunnels with kegs of powder and floated up to within four hundred yards of the fort. When it was finally exploded, its effect upon the fortress was so slight that the Confederate soldiers inside thought it was merely a boiler explosion from one of the besieging vessels. General Butler and his assistant, General Witzel, however, landed their forces, hoping to find the garrison in a state of confusion and discouragement. General Butler found that the explosion had simply aroused rather than dismayed the besieged. From all along the ramparts as well as from the tops of the inner bastions a tremendous converging fire was poured upon the attacking force. Back of these fortifications were grouped some of the best sharp-shooters of the whole Confederate Army and after a few minutes of disastrous fighting, General Butler was glad enough to withdraw his forces back to the safety of the ships. He refused to renew the battle and reported to General Grant that Fort Fisher could not be taken by assault. General Grant was so disgusted by this report that he at once relieved General Butler of the command and this battle was the end of the latter's
