Operation Avalanche

3 Sep 1943 - 17 Sep 1943

Contributor:

ww2dbaseHaving driven Axis troops out of the island of Sicily by 17 Aug 1943, the Allies launched Operation Avalanche, the invasion of mainland Italy. Given a choice of two landing sites, the opening of the Volturno River north of Naples or Salerno southeast of Naples, the latter was chosen as it had landing beaches favorable to invaders and it had nearby major roads and airfields that could be used by the Allies after a successful invasion. Operation Baytown and Operation Slapstick were launched to prepare for the main Operation Avalanche invasion, although the latter was actually commenced on the same day as Operation Avalanche.

ww2dbaseOperation Baytown was embarked upon by British XIII Corps under the command of Bernard Montgomery. On 3 Sep 1943, six days prior to the Salerno landing, British and Canadian troops landed at Reggio Calabria at the southwestern tip of Italy, intending to tie down German troops in southern Italy and perhaps even drawing German troops away from the Salerno area further north. This operation ultimately did not achieve its intended effect as the German commander-in-chief Albert Kesselring correctly deduced the main Allied target was further north up the coast; instead of keeping troops south to counter the British-Canadian attack, Kesselring actually gradually pulled German LXXVI Panzer Corps back, leaving only a single regiment and some Italian formations to deal with the Baytown invasion.

ww2dbaseOperation Slapstick, which saw the amphibious landing of Taranto and Brindisi in southeastern Italy, was conducted by troops of British 1st Airborne Division. Although two port cities had been secretly made available to the Allies during the secret armistice negotiations, Allied Supreme Commander Dwight Eisenhower decided to land a large number of troops there as another attempt to draw German attention away from the Salerno landings. The four British cruisers that carried the invasion troops arrived at Taranto at 1500 hours on 9 Sep, where they were guided through the defensive minefield by the Italians as previously agreed upon. The Taranto landing was met with no resistance as German troops had already been pulled back per Kesselring's orders days prior. Two days later, the British paratroopers captured Brindisi, again without resistance, although along the way the advance was met with German harassment. On the same day, the British paratroopers who pushed westward linked up with Canadian troops of XIII Corps. The Slapstick offensive would push on to capture the airfield at Gioia del Colle in mid-Sep 1943, after which it would be halted to consolidate the territorial gains. The British paratroopers would be withdrawn to Britain by Nov 1943.

ww2dbaseThe main Operation Avalanche offensive against Salerno took place on 9 Sep 1943, the same day as the Taranto operation. To gain an element of surprise, the landing commenced without pre-invasion naval and aerial bombardment, but Allied leadership did not know that Kesselring had already been preparing for a possible invasion in the general region, thus no surprise could truly be achieved. The 165,000-strong Salerno invasion force, US Fifth Army under the command of Lieutenant General Mark Clark, was consisted of US VI Corps (Major General Ernest Dawley), British X Corps (Lieutenant General Richard McCreery), and US 82nd Airborne Division in reserve. Despite the broad 56-kilometer front, only three divisions, two British and one American, made up the initial assault force, with the British landing north of the Sele River near Montecorvino and the Americans to the south of the river at Paestum. A small force of US Rangers and British Commandos would land northwest of the British landing beaches to secure the roads leading to Naples up the coast.

ww2dbaseOpposite the Allies stood several German divisions, all of which had been vigilant of an Allied attack as warned by Kesselring.

ww2dbaseAt Paestum, the two inexperienced battalions of US 36th Division which landed first nearly fell into disarray when they faced enemy fire, but was able to hold the beachhead as the next wave of troops arrived. The British troops further north were able to push inland for about 8 to 11 kilometers. Through the following three days, both sides built up their strength in the region, but it would be the Germans who would reach their desired level of strength (six divisions) first for a major offensive, while Allies shifted to a defensive stance. The German counterattack began on 13 Sep, with the main attack striking in the region near Battipaglia, intending to divide the British X Corps and the US VI Corps. The afternoon of 13 Sep saw Allied units, mainly the Americans as the German efforts focused more in the Sele River region, being pushed back and suffering heavy casualties in the process; two battalions of US 82nd Airborne Division were brought in to help hold the line. In the afternoon on the following day, US 180th Infantry Regiment arrived near Paestum, relieving the paratroopers. The German advances were slowed on 15 Sep, largely because of heavy naval gunfire and aerial bombardment. On 16 Sep, German troops launched a second attack against positions held by troops of British X Corps, but made little progress.

ww2dbaseMeanwhile, Bernard Montgomery's force which had participated in Operation Baytown slowly made their way up Italy. By 16 Sep, British 5th Infantry Division had reached Sapri, less than 100 kilometers southeast of Salerno, thus nearly linking up the two forces. In light of the German inability to drive off the Allied invasion, and the now near link up of two large Allied forces, Kesselring was advised by German Tenth Army commanding officer Heinrich von Vietinghoff to call off the offensive, fall back, and form a defensive line; Kesselring agreed with this suggestion and gave such orders on 17 Sep. Kesselring believed that even as he gave the Allies control of Salerno, the terrain of Italy would prove to be favorable for defense. Together with his orders to pull back from Salerno were orders to destroy key bridges and other means of transportation to frustrate future Allied advances.

ww2dbaseRealizing the Germans were pulling back, British and American troops of US Fifth Army began marching toward Naples on 19 Sep. By the end of the month, the southern portion of Italy was under Allied control, including the major airfield complex near Foggia, which was captured on 27 Sep.

Wait, i got kinda confused here, lol. It says that Eisenhower took troops to land in Taranto to draw the Germans out of Salerno. But then it says "The Taranto landing was met with no resistance as German troops had already been pulled back per Kesselring's orders days prior." Weren't the Germans AT Taranto?
