FAILURES—7. Fort Donelson, Fort Darling, Dutch at Simonoseki, Americans at Simonoseki, Fort McAllister, Danube forts, Callao. Of the partial successes, all six accomplished the objects of the bombardment. In that of Kagosima the Japanese were brought to terms, and the other five had for their object to silence the forts, which they accomplished. Of the failures, the two attacks on Simonoseki were retaliatory measures, and would probably have succeeded had they been kept up longer. Fort Darling and Fort McAllister were experimental tests, although there are no grounds to believe that the forts would have been silenced had the action been kept up longer. At Fort Donelson, the Danube forts, and Callao the ships were beaten. BOMBARDMENTS OF MASONRY FORTS. _Attack on Fort Sumter, April 7, 1863._ FEDERAL. IRON-CLAD SQUADRON. Guns.
