"Dulce et Decorum Est" is a poem written by Wilfred Owen, a British soldier and poet during World War I. The poem vividly depicts the harsh realities of war, contrasting the romanticized notion of dying for one's country with the brutal experiences of soldiers on the battlefield. The title translates to "It is sweet and honorable," referencing a line from the Roman poet Horace. Owen challenges this idea by illustrating the physical and psychological suffering of soldiers, particularly through graphic imagery of a gas attack, ultimately conveying the message that war is far from glorious.
