With the start of this war, the monitor was towed from Callao to the south of Peru to defend the bay of the Peruvian port of Arica, its boilers were repaired and it was propelled at a speed of 2 knots. During the blockade of Arica, the ex-Peruvian turret ship Huáscar, captured by the Chileans at the Battle of Angamos in 1879, attacked the Peruvians at the port of Arica on 27 February 1880, fighting an inconclusive duel with Manco Cápac. The ex-Peruvian ironclad Huáscar failed in her attempt to ram the Peruvian monitor and the Huascars captain was killed in this engagement of the Naval Battle of Arica. The Chilean fleet continued to blockade Arica as the army closed in on the city from the rear.
