The song "Canción Del Esposo Soldado" (Song of the Soldier Husband) was written and performed by Spanish singer Joan Manuel Serrat. The lyrics depict the emotional journey and sacrifice of a soldier who is also a husband. The soldier expresses his love and devotion to his wife, symbolized by the image of populating her womb with love and fertility ("He poblado tu vientre de amor y sementera"). He compares himself to a plow waiting on the furrow, ready to protect and provide for his family. Despite being separated by war, he still feels connected to his wife, extending his love to her even in battle. The soldier acknowledges the danger he faces, being surrounded by bullets and targeted by bullets ("Mujer, mujer, te quiero cercado por las balas, Ansiado por el plomo"). He asks his wife to write to him and feel his presence in the trenches, as he fights and defends her and their unborn child. The soldier believes that killing is a necessary evil for him to continue living and protecting his loved ones ("Es preciso matar para seguir viviendo"). He dreams of a future where he can find solace and rest in his wife's comforting embrace, represented by her distant hair and a loud, starched sheet ("Un día iré a la sombra de tu pelo lejano, Y dormiré en la sábana de almidón y de estruendo"). This emphasizes the soldier's longing for peace and the simple joys of domestic life. In the end, it is revealed that the soldier's ultimate goal is to create a world of peace for his child ("Para el hijo será la paz que estoy forjando"). The song concludes with the imagery of the husband and wife worn out by their passionate kisses, with their hearts eventually sinking and merging in the ocean of inevitable bones ("Tu corazón y el mío naufragarán, quedando, Una mujer y un hombre gastados por los besos"). Overall, the song portrays the soldier's love, sacrifice, and longing for his wife and unborn child amid the hardships of war. It highlights the universal human desire for peace and the hope that love can endure despite the challenges faced by those in conflict.
