Battle of Monte Cassino
Contributor: C. Peter Chen
ww2dbaseThe Allies reached the western end of the German Gustav Line in Italy in mid-Jan 1943. The main German positions generally ran along the valleys created by the Rapido River, Liri River, and the Garigliano River. German troops established positions on the hill of Monte Cassino, which dominated over the valleys, but they had stayed out of the nearby historical Benedictine monastery per orders of Field Marshal Albert Kesselring.
ww2dbaseBritish X Corps, consisted of 56th Infantry Division and 5th Infantry Division, attacked first on 17 Jan 1944, crossing the Garigliano River near the coast on a 20-mile-wide front. Two days later, British 46th Infantry Division attacked near the junction of the Garigliano River and the Liri River. In response, German 29th Panzergrenadier Division and 90th Panzergrenadier Division were called in from the Rome, Italy area to reinforce the defenses, arriving on 21 Jan. What was considered to be the main assault, conducted by US 36th Division, began shortly after sundown on 20 Jan 1944. Troops of US 141st Regiment and 143rd Regiment were able to cross the Rapido River, but timely German counterattacks by German 15th Panzergrenadier Division caused heavy casualties, and the Americans were eventually pushed back across the river by mid-morning on 21 Jan. After sundown, the two US regiments established new footholds on the far side of the river, only to be eliminated again after dawn on 22 Jan; those established by US 143rd Regiment were destroyed in the morning, while those by US 141th Regiment were destroyed in the evening. In these failed attempted to cross the Rapido River, US 36th Division suffered 2,100 casualties. On 24 Jan, US 34th Infantry Division, with French Moroccan colonial troops also in its ranks, crossed the Rapido River north of Cassino where the terrain was unsuitable for vehicles for both sides. Infantrymen engaged in bitter fighting for the following week, and on 1 Feb, troops of German 44th Infantry Division which had opposed the Allies fell back toward Monte Cassino, finally allowing the Allies a solid foothold on the previously German side of the river. Tough fighting continued, but the Americans were generally able to push forward, capturing Point 445 on 7 Feb and attacking (but failing to take) Point 593 shortly after. A renewed attack toward Monte Cassino was launched on 8 Feb, but after three days of heavy fighting and no apparent success, the assault was called off on 11 Feb. While the Americans suffered very heavy casualties in the failed attempts to advance, the Germans suffered similarly. In fact, the German front line divisions had suffered such a high casualty rate that some German generals wondered if the western end of the Gustav Line should be abandoned in favor of the next defensive line to the north already being prepared, but Kesselring rejected such notions.
ww2dbaseMeanwhile, the Allies launched Operation Shingle which landed 36,000 men at Anzio, Italy on 22 Jan 1944. In an attempt to assert pressure on the Gustav Line in coordination with the attack on Anzio, Operation Avenger was launched. Similar to the first attempt to take Monte Cassino, the Allies, largely consisted of New Zealand and Indian troops in this offensive, suffered heavy casualties to accurate German artillery shelling into the valleys. Since the artillery fire came from up above, Allied leadership believed that the Germans must have observation posts near or within the Benedictine monastery. Aerial reconnaissance missions conducted over the abbey did not consistently produce evidence that there were German troops stationed inside. Some of the Allied generals believed that even if the Germans were not already using the high ground at the monastery grounds, all efforts should be expended to prevent the Germans from doing so. On 11 Feb, Brigadier Harry Dimoline, acting commanding officer of Indian 4th Division, requested aerial bombing of the monastery, which was passed on by Lieutenant General Bernard Freyberg to the air forces. The bombing was approved and conducted on 15 Feb, with 229 US heavy and medium bombers dropping 1,150 tons of high explosive and incendiary bombs, demolishing nearly all structures; the aerial bombing was augmented by artillery shelling as well. On the following day, while artillery shelling continued, 59 fighter-bombers attempted to destroy whatever remained standing. Point 593, the German strongpoint beneath the abbey that the Allies attacked but failed to take in early Feb, was nearly untouched by the attacks. Interestingly, the Allies failed to immediately launch a major ground assault immediately after the bombing (though a company of 1st Battalion of British Royal Sussex Regiment of Indian 4th Division did indeed attack Point 593, failing to take it). With the Monte Cassino monastery in ruins and thus no longer of cultural and historical value, troops of German 1st Parachute Division moved in and precisely used it as an observation post as Allied leadership had feared. In the night of 17 Feb 1944, Indian 4th Division and the New Zealand Division attacked Monte Cassino in strength; a parallel attack by 28th (Maori) Battalion of the New Zealand Division successfully established a small bridgehead across the Rapido River, but this bridgehead would be lost again on the following day.
ww2dbaseThe third major Allied attempt to take Monte Cassino was launched on 15 Mar 1944, which began by a heavy bombardment that lasted more than three hours. When the New Zealand troops spearheaded the attack, they were met with a stronger German defense than what they had expected. Although the initial attacks did capture several positions including Castle Hill, Point 165, and Point 236 through 16 Mar, heavy rain slowed the Allied progress. By the end of the day on 17 Mar, a battalion of Indian Gurkha troops, having captured Point 435, were within 250 meters from the monastery while New Zealand troops were threatening to capture the town of Cassino. Several attacks were launched successively over the course of the next several day; while limited progress were made with each attack, by 23 Mar, signs of exhaustion in the Allied divisions were obvious, and on that date Harold Alexander and Bernard Freyberg both agreed to pause the offensive. On the other side of the line, German 1st Parachute Division was begining to feel the pressure as well; many of its units were now grossly under-strength.
ww2dbaseThe fourth and what was to become the final offensive on Cassino, codenamed Operation Diadem, was launched several weeks later in the night of 11-12 May 1944. An impressive artillery bombardment by British, American, Polish, New Zealand, South African, and French guns opened the operation, and by the dawn on 12 May some of the Allied units had made significant advances, particularly the success of Indian 8th Division in establishing a bridge over the Rapido River to bring forth tanks of Canadian 1st Armoured Brigade. During the day of 12 May, Polish troops briefly captured Monte Calvario, codenamed Point 593 by the Allies, but by the end of the day the position would again be lost to the German paratroopers. By 13 May, Germans lines began to buckle under pressure as French troops captured Monte Maio while US 5th Army overran several German positions in the Liri River valley. As German positions along the Liri River valley began to fall one by one, troops of the Polish Corps launched what was to become the final attack on Monte Cassino on 17 May; they would succeed in taking the ruins of the mountaintop monastery by the following day after the Germans evacuated their positions overnight, leaving behind only thirty seriously wounded men to be captured.
ww2dbaseGerman troops fell back from the Gustav Line to the Hitler Line 13 kilometers to the north, which was quickly renamed the Senger Line (ie. removing Hitler's name from the defensive line) as the Germans knew it would only be a matter of time before these positions would have to be abandoned. Polish and Canadian troops assaulted the line on 23 May, and on the following day the line was breached, forcing the Germans to fall back toward the Caesar C Line, the final line of defense south of Rome.
ww2dbaseThe four-month long campaign for Cassino cost the Allies about 55,000 casualties. Though defeated, the Germans suffered only about 20,000 casualties.

My Grandfather lost his life at Cassino on the 3rd Dec 1943. He was part of the British 8th Army in the Royal Signal Corps. Is there anyway I can find out exactly where he was killed because on a recent visit to Cassino I was told the attack by the allies there did not start until Jan 1944

@nigel Adamthwaite you should connect with Danila. She is an expert on WWII history particularly the Montecassino campaign. She gave my classmates and I a tour and she's known for re-connecting families with their past and providing families proof for what happened to them. This is her tripadvisor page. I really think she can help you.

My dad was on this bombing mission for the Americans. He was Chief Crew mechanic on the "Scragg Boys" B-17 and snuck aboard, not knowing the destination of the mission, it was classified and none of the crew knew. Such a disaster
