se volunteers During the first 4 days of
insurgency Utrilla acted as head of Carlist regional
general staff. He was busy mostly organizing the avalanche of volunteers, forming units, nominating commanders, deploying troops in specific directions and raising morale by delivering public addresses. Apart from Navarre, he helped to organize the rebellion also in the neighboring
Álava. His crucial contribution, however, consisted of heading a 1,200-strong column of Navarrese requetés which on July 23 moved by train from Pamplona to
Zaragoza. The convoy was organized as urgent emergency measure, since insurgents’ control over the
Aragonese capital was extremely shaky. Utrilla enforced swift transport and then ensured rebel domination in the city; with
Jesús Comín he was also the one who made the local rebel military commander,
general Cabanellas, to replace the republican flag with the monarchist
roja y gualda. In early August he handed over command of the requeté troops in Zaragoza, to honor the Carlist queen already named Tercio de
María de las Nieves, and returned to Pamplona. Utrilla spent most of August in Pamplona; on the last day of the month he left for the
Gipuzkoan front. In early September he was back in combat since the Moroccan times of 1925; on approaches to
Irún he commanded a heterogeneous unit which consisted of requetés,
Falangists and soldiers, 6 companies in total. It formed part of so-called Columna Los Arcos and
assaulted the fortified outpost of San Marcial; it overran
Behovia on September 4. In mid-September he advocated shuttling some troops from Gipuzkoa to Aragón; following the seizure of
San Sebastián, in mid-month he indeed led some of the requeté sub-units transferred East. He resumed command over Tercio María de las Nieves, most of it deployed on defensive positions along the Ebro. Utrilla remained in charge until November, when he handed over to José Medrano. Utrilla's whereabouts during the winter of 1936-1937 are not clear. In March 1937 he was listed in the official order of the
Nationalist high command, already in the regular army service; as comandante retirado he was assigned to head Cuadro Eventual of the 6. Division, to be raised in
Granada. His later service record is not known; a press note from late 1937 hailed his contribution to victorious
Northern campaign, but provided no details. A contemporary historian speculates that Utrilla served in Jefatura de Milicias, the section of Nationalist general staff entrusted with organization of militia units, formally incorporated into the army but allowed a grade of autonomy. In June 1938 he was – again, following the annulled 1929 elevation – promoted to coronel de caballería. None of the sources consulted provides information on his assignment during final phases of the Civil War. ==Post-war military career==
