"Ya salimos"

This is a reference to 'Viva la Quince Brigada', a song sung by the Lincoln Battalion, an American volunteer group, during the Spanish Civil War. The music comes from an old Spanish folk tune, and the lyrics refer to the battle at Jerama Valley:

 

En los frentes de Jarama
Rumbala, rumbala, rum-ba-la (repeat)
No tenemos ni aviones
Ni tanques, ni canones, ay Manuela! (repeat)
Ya salimos de Espana
Rumbala, rumbala, rum-ba-la (repeat)
Par luchar en otros frentes
Ay Manuela, ay Manuela!
At Jarama we are standing
Rumbala, rumbala, rum-ba-la
And we have no planes above us
Not a tank, nor any canons, ay Manuela!
We have left the Spanish trenches
Rumbala, rumbala, rum-ba-la
To fight the Fascists where we find them
Ay Manuela, ay Manuela!
