[1] Nuestra Señora del Triunfo′s first assignment was to the Training Squadron, which was under the overall command of Contralmirante (Counter Admiral) Luis Hernández-Pinzón Álvarez.

[1][2] The two screw frigates entered the Arsenal de La Carraca at San Fernando to fit out for their deployment to the southeastern Pacific Ocean.

[1] The four ships got underway from Montevideo on 10 January 1863[4] and proceeded down the coast of Patagonia, passed the Falkland Islands, rounded Cape Horn on 6 February 1863,[5] and entered the Pacific Ocean.

[1] With tensions spiking between Spain and Peru, Nuestra Señora del Triunfo and Resolución covered an operation in which many of the Spaniards in Peru embarked on the steamer Heredia at Callao and Virgen de Covadonga towed Heredia out of the harbor under the guns of Peruvian Navy warships that were ready to open fire.

[1] Spain and Peru avoided war, but Pinzón resigned his command on 9 November 1864 because he felt that the Spanish government had not supported his actions, and Contralmirante (Counter Admiral) José Manuel Pareja took charge of the Pacific Squadron.

[1] While her commanding officer was aboard Resolución for a meal with Pareja, Nuestra Señora del Triunfo′s crew began storing the supplies Tampico had delivered.

[1] Nuestra Señora del Triunfo′s gunpowder magazine was flooded to prevent a catastrophic explosion, but by nightfall the fire had spread out of control.
