Czerwone maki na Monte Cassino (The Red Poppies on Monte Cassino) is one of the best-known Polish military songs of World War II. It was composed in May 1944 in Italy, during the Battle of Monte Cassino, on the eve of the Polish Army's capture of the German stronghold.
In early 1944 a German stronghold, dug in at the ancient Benedictine monastery atop Monte Cassino, had blocked the Allies' advance toward Rome. The forces of several Allied countries had attempted since mid-January to capture the German fortress. For a fourth major assault, which would begin on 11 May 1944, Polish troops were rotated in. On 18 May 1944, the day following the song's composition, the Poles stormed and captured the precincts of the Monte Cassino monastery. Later that day, the song was first performed at General Anders' headquarters to celebrate the Polish victory. The Red Poppies on Monte Cassino won popularity with the troops and was soon published by a Polish-American newspaper in New York. It would later be published in Poland. It was banned, however, during the Stalinist period in the People's Republic of Poland, when the government sought to minimize memory of the wartime Polish Armed Forces in the West
