Quick answer

The Allies won the Battle of Monte Cassino in 1944 after four months and four assaults on the German-held mountain and abbey that blocked the road to Rome. Soldiers from across the world bled on its slopes; in the fourth battle, in May 1944, the Polish II Corps stormed the heights and raised its flag over the ruins.

For four months in 1944 the Allied advance on Rome was blocked by a single mountain crowned with an ancient abbey: Monte Cassino. Three assaults broke against the German defences, and soldiers from across the world, American, British, New Zealander, Indian, French and Moroccan, bled on its slopes. In the fourth, in May 1944, it was the Polish II Corps that stormed the heights and raised its flag over the ruins, and the road to Rome was open.

The gateway to Rome

After landing in Italy in 1943, the Allies were stopped by the German Gustav Line³, anchored on the high ground around Monte Cassino. The mountain and its ancient Benedictine abbey dominated the Liri valley and the road to Rome. The Germans held the surrounding heights in great strength, and for months every Allied push up the valley was stopped cold.

Four battles for one mountain

Between January and May 1944 the Allies launched four separate offensives at Cassino⁴. American, British, New Zealand, Indian and French troops fought and died on the slopes and in the ruined town. In February the historic abbey was bombed to rubble on the belief it was being used by the defenders, though at the time no German troops were inside⁵; the Germans then fortified the ruins⁵, which became even harder to take.

Armies from across the world broke on that mountain; the Poles took it at last.

The Poles take the heights

The final assault in May 1944 fell to the Polish II Corps under General Wladyslaw Anders, men who had marched out of the Soviet Union to fight. In ferocious close-quarters fighting for Hill 593 and the monastery⁶, they suffered heavy losses, fell back, and attacked again. On 18 May 1944 the Poles took the ruins² and raised the Polish flag over Monte Cassino.

The cost and the legacy

With the Gustav Line broken, Rome fell to the Allies on 4 June 1944⁷. The four battles had cost the Allies tens of thousands of casualties. For Poland the mountain became sacred ground: the Polish war cemetery lies below the abbey, and the song of the red poppies of Monte Cassino turned the sacrifice, made far from a homeland they could not freely return to, into a lasting national symbol.
