"A Wife in London," by Thomas Hardy, explores the profound impact of war on domestic life through the lens of a woman awaiting her soldier husband during the Second Boer War. The poem uses vivid imagery, including fog-laden London, to depict the uncertainty and despair the wife experiences upon receiving news of her husband's death. Hardy examines the themes of loss, isolation, and the contrasting experiences of love and grief, highlighting the broader societal implications of war and the toll it takes on those left behind.
