Christians win the battle of Las Navas de Tolosa against the infidel mours and start to thank God almighty for their victory, as this was the greatest victory for christians in Reconquista

Te Deum laudamus: te Dominum confitemur.
Te æternum Patrem amnes terra veneratur.
Tibi omnes Angeli; tibi cæli et universæ Potestates;
Tibi Cherubim et Seraphim incessabili voce proclamant:
Sanctus, Sanctus, Sanctus, Dominus Deus Sabaoth.
Pleni sunt cæli et terra maiestatis gloriæ tuæ.

Te gloriosus Apostolorum chorus,
Te Prophetarum laudabilis numerus,
Te Martyrum candidaus laudat exercitus.
Te per orbem terrarum sancta confitetur Ecclesia.
Patrem immensæ maiestatis:

Veneradum tuum verum et unicum Filium;
Sanctum quoque Paraclitum Spiritum.

Tu Rex gloriæ, Christie.
Tu Patris sempiternus es Filius.
Tu ad liberadum suscepturus hominem, non horruisti Virginis uterum.

Tu, devicto mortis aculeo, aperusti credentibus regna cælorum.
Tu ad dexteram Dei sedes, in gloria Patris.
ludex crederis esse venturus.

Te ergo quæsumus, tuis famulis subveni:
quos pretioso sanguine redemisti.
Æterna fac cum sanctis tuis in gloriæ numerari.

Salvum fac populum tuum, Domine, et benedic hereditati tuæ.
Et rege eos, et extolle illos usque in æternum.
Per singulos died benedicmus te;
Et laudamus Nomen tuum in sæculum, et in sæculum sæculi.
Dignare, Domine, die isto sine peccato nos custodire.
Miserere nostri Domine, miserere nostri.
Fiat misericordia tua, Domine, super nos, quemadmodum speravimus in te.
In te, Domine, speravi: non confundar in æternum.

Te Deum Laudamus

The "Salve Regina" is the famous prayer "Hail, holy Queen" which is commonly prayed at the end of the Holy Rosary and is traditionally sung after Compline from Saturday before Trinity Sunday until the Friday before the first Sunday of Advent. It is attributed to Bl. Hermannus Contractus (aka Hermann of Reichenau) in the 11th century, but in its current form comes from the great Abbey of Cluny in the 12th century.

Hailed by The American Spectator (2020) for his “energetic” leadership and his role in restoring “the Roman Rite in all its solemnity and splendor,” Nick Botkins is an organist and conductor known for his liturgical instinct, expressive improvisation, and deep command of the Church’s musical tradition. He serves as Organist and Choirmaster at the Basilica of Saint John the Evangelist in Stamford, Conn., where he directs the professional Schola and curates a repertoire spanning more than a millennium of sacred music.

In addition to his work at the Basilica, Mr. Botkins serves on the faculty of Cardinal Kung Academy in Fairfield County, where he teaches music theory and directs the Cardinal Kung Academy Schola Cantorum and Boychoir. He is particularly noted for his expertise in Gregorian chant, Renaissance polyphony, and the orchestral Mass tradition.

As an organist, he has performed throughout the United States and Europe, including to enthusiastic audiences at Westminster Cathedral (London), Saint-Eugène (Paris), the National Convention of the National Association of Pastoral Musicians (St. Louis), and regional events of the American Guild of Organists. His performances have been broadcast by the Radio Arts Foundation, USA.
