The poem explores the theme of nostalgia experienced by mercenary soldiers away from their mountain homes. In vivid detail, the first two stanzas describe the soldiers' physical and emotional suffering as they long for the high altitudes, familiar tastes, smells, and sounds of their homeland. Leaving came with "a sweet pain in the heart" and hurt to hear the "music of home" summoning them back. The final stanza depicts the changed reality upon one soldier's return, finding the same streets but everything different, reflecting how nostalgia transforms perceptions of place and past. Overall, the poem elicits sympathy for how wartime service forces soldiers to grapple with displacement and loss of innocence about home.
