Freely translated some parts, but I think the translation still makes sense.
As the Spanish Civil War began in 1936, the Iron Guard, like much of the Romanian public opinion, saw it in a simple dichotomy: a fight between atheistic communism and Christianity, this point being made stronger by the news that some groups on the Republican side systematically persecuted members of the Catholic clergy and destroyed churches.
Ion Moța, the second in command in the Legion, suggested that a number of leaders of the Iron Guard would go to Spain and present a gift (a Toledo sword) to Francoist General José Moscardó Ituarte, then fight alongside the Nationalist forces. They were involved in the battles near Madrid, and on January 13, 1937, at Majadahonda, Ion Moța and Vasile Marin were killed by an artillery shell.
The bodies of the two members of the Legion were put in a mortuary train which left Spain, via France and then Belgium, reaching Berlin on February 6, 1937, where they were met by SS and SA squads, representatives of the German Nazi Party, of the Spanish Falange and of Fascist Italy as well as a big crowd.
After going through Poland, the February 9, the train reached the Romanian border, but instead of taking the shortest route to Bucharest, it made a detour by going through the whole country, from Bukovina to Moldavia, then Transylvania, Oltenia, Wallachia and finally reaching Bucharest.
It was in Bucharest that the biggest procession took place: as the government lifted the ban of wearing uniforms in public places, thousands of Legionnaires wearing their green uniforms waited for the coffins in front of the railway station. Further tens of thousands of Bucharesters were just sympathisers or simply bystanders who watched the procession and followed it through the city.
In addition, a big number of Romanian politicians, professors and students, as well as diplomatic staffs from Italy, Germany and Spain, as well as representatives of the Fascist parties in these countries were present.
After a short religious service, in front of the coffins, the Legionnaires performed the "Ion Moța and Vasile Marin Oath", an oath written by the leader of the Iron Guard, Corneliu Zelea Codreanu. In this oath, they swore that they are "ready for death at any time".
The procession marched toward Saint Ilie-Gorgani Church in central Bucharest, where the bodies were to be kept until their burial. The funeral procession was led by some Iron Guard members who carried the crosses of the two fighters, followed by students, representatives of Hitler, Mussolini and Franco, a large number of priests and a Legionary formation in the shape of a cross.
Moța and Marin were interred on February 13, 1937, next to the Headquarters of the movement, the "Green House" (Casa Verde), in a mausoleum specially-built, a decision made by Codreanu in order to inspire the future Legionnaires. The religious services were held by a number of between 200 and 400 priests.
Five surviving Legionnaires who fought in Spain took a part in the next part of the procession. Pedro de Prat y Soutzo, the Nationalist Spain's diplomatic representative called the names of those in the legionnaire squad, and for Moța and Marin, everyone answered "Present!". A similar roll call was found in other fascist movements, too; for example it was the focal point in the 1932 Garibaldian Celebrations, in Mussolini's Italy.
Lyrics:
Sunt ruguri de flăcări. E Spania-n scrum.
Gloanţele cad în altar.
În negrele şanţuri cu sânge şi fum,
Plouă cu schije şi jar.
Dar sub obuze,
Gloanţe şi spuze,
Par legionarii nişte munţi...
Rănită-n zare,
Crucea le-apare
Şi ceru-i mângâie pe frunţi.
Noaptea-n tranşee legionarii,
În ploaie îşi fac rugăciunea...
Mintea lor trece fruntarii
Şi-n gând li s-aprinde Legiunea,
Şi văd Căpitanul şi ţara
Cu sfântu-i destin legionar.
Obuzele tună, împroaşcă oţel...
Tancuri pornesc ca din iad.
Şi Moţa e-n frunte, Marin lângă el
Roşii, grenadele cad...
Printre reţele,
Mine, şrapnele,
Schijele plouă fier de sus.
Loviţi în frunte,
Cu braţele frânte,
Cad legionarii lui Iisus.
Moţa în şanţ plin de sânge,
Şopteşte murind rugăciunea:
„Moartea la pieptu-i ne strânge
Să crească mai mândră Legiunea.
Să faci, Căpitane, o ţară
Ca soarele sfânt de pe cer!"
