At daylight on the 8th the Chilian iron-clad corvette Blanco Encalada sighted the Peruvian iron-clad turret-ship Huascar, and gave chase. The Huascar, running to the northward, and slowly distancing the Blanco, was headed by the Chilian iron-clad corvette Almirante Cochrane. These two ships then engaged, and in about half an hour the Blanco closed and opened on the Huascar, placing her between two fires. After an action of one hour and a half the Huascar surrendered, having been much cut up, and having lost her three senior officers. Casualties: Blanco Encalada, none. Almirante Cochrane, 2 killed, 10 wounded. NOTE.—After careful research it has been found that in every case cited in which boilers were penetrated by projectiles, the part of the boiler hit was _above the water-line_. PART II.
