depicting Ugarte's death in Arica. Ugarte was head of the Eighth Division in the defense of the city of Arica, where he participated in the two military councils held by Colonel
Francisco Bolognesi, where the agreement was made to defend the bastion "until the last round is spent" (). The
Battle of Arica took place on June 7, 1880. According to witnesses, Ugarte stated that "not even the tail" of his horse would be touched by the
Chilean Army, and ultimately rode his horse over the
Rock of Arica in order to prevent the Peruvian flag, which he was carrying, from being captured. Fifteen days later, the testimony appeared in
La Patria, a newspaper based in Lima. This event is also recalled by Sir
Clements Markham in his works about the conflict. A Chilean officer of the Mountain Detachment "Yungay" No. 3 also documented the event in a report. In 1881, Chilean historian
Benjamín Vicuña Mackenna wrote that on December 17,
Nicolás de Piérola ordered that the southernmost defense redout in
Lima be named after Ugarte, described by Vicuña as the "bizarre youth that, like La Rosa in Iquique, had jumped to the ocean" following the battle. Ugarte's body was found at the bottom of the cliff, according to a recorded statement by José Diego Chávez, then priest of Arica, dated June 15, 1880. He was buried at a grave at the local cemetery, where he would remain buried until 1890, when a number of bodies were moved to Lima. On July 8, 1880, is 15-page last will and testament were read in
Arequipa. In 1890, a ceremony where a group of important
tarapaqueños took his coffin to the mausoleum of
Ramón Castilla took place. Years later, his body was taken to a mausoleum built by his mother in the
General Cemetery of Lima. In 1979, historian authorised the inspection of the body, his garments, and the flag. == Legacy ==
