...that his only choice was solitary slumber!
!كان خياره الوحيد النّوم العميق بمفرده
¡él tuvo que reposar en soledad!
¡él tuvo que reposar en soledad!
alors il s’est plongé
dans ce sommeil solitaire.
è stato costretto a un sonno triste e solitario!
ele não teve escolha, a não
ser cair em um sono solitário.
поэтому ему пришлось
заснуть одиноким сном!
