Roadside monument about 1.1 KM east of Huesca. Location (within ten meters): 42°8'27.90"N, 0°22'23.16"W.
According to Wiktionary, “requetés” could mean soldiers fighting for Carlos 1833–1840 or soldiers fighting for Franco 1936 to 1939. I don't know which, but I'm guessing the latter, as this thing doesn't appear to be 150 years old.
Anyone know for certain?
The inscription reads (with spelling corrections):
Señor, tened piedad de los requetés del tercio de Doña María de las nieves que aquí murieron por vuestra santa causa y la de España. R.I.P.
Lord, have mercy on the recruits of the Regiment of Doña María de las Nieves who died here for your holy cause and that of Spain. R.I.P.
