Huáscar's raids force Chile to change commanders

For roughly six months Huáscar avoided Chile's stronger ironclads while attacking maritime communications and supporting Peru's war effort. Her capture of the steamer Rímac also took an embarked Chilean cavalry regiment, producing the army's largest loss of the war to that point. The political shock forced the resignation of Chilean fleet commander Juan Williams Rebolledo. His replacement, Galvarino Riveros Cárdenas, then designed the coordinated operation that trapped Huáscar at Angamos, showing how successful commerce raiding can provoke organizational change as well as material loss.
