The phrase "Ast illi solvuntur frigore membra vitaque cum gemitu fugit indignata sub umbras" in English translates to "But their limbs grow stiff with cold, and life, indignant, flees with a groan into the shadows." This line is from Book 4 of Virgil's Aeneid, describing the death of soldiers in battle. It portrays a vivid image of the soldiers succumbing to the cold and death.
