Operation Husky: Moving Inland

Gen. Alexander's plan was to have a firm base and assemble his forces in a line from the port of  Licata to Catania before moving inland.

In order to accomplish this, it was necessary to capture ports and airfields to facilitate the build-up of forces. Hence the 8th Army was tasked to capture the airfield of Pachino, and then move north to capture ports of Augusta and Catania, whereas the 7th Army was tasked to capture Licata, and then cover the 8th Army's western flank and prevent enemy reserves.
On the morning of 13 July, elements of the 5th division on the 8th army's left flank, entered the town of Augusta, but they were successfully grounded by German counterattacks supported by the Napoli division. Meanwhile, the British 50th Infantry had pushed up along highway 114 towards Lentini, 15 miles North-west of Augusta, meeting resistance from Italian R-35 Tanks and some infantry from the Napoli division.

The Italian tank commander and his staff were captured by the elements of the 4th Armored brigade, and by 1900 hrs 14th July, the town had been cleared of any lurking Snipers or Infantry.
Further left, the Canadians had successfully secured the Pachino landing fields, and headed Northwest to link up with the Americans at Ragusa port after defeating the Italian 122nd Infantry. 
In the Canadian sector, an area under Brig. Robert E. Laycock was attacked by the 206th Coastal Infantry in a last-ditch counterattack. Fortunately, there was a heavy-mortar unit on alert nearby, and hence were able to break the attack.
On the 16th of July, Sicilian air command ordered all surviving squadrons to the mainland. On the night of 17th July, Montgomery renewed his attack on Catalina with two brigades from the 50th. After strong resistance, the attack was called off by 19th, and he continued to push on his left. On 20th July, the 51st Division crossed the river Dittiano and made for the airfields near the town of Gerbini. Even these met with exceptionally strong resistance.
The Canadians continued their northward sweep on the 8th Army's far left flanks. But as German troops settled into their new positions, they realised that their strength was insufficient to carry on the whole front. Hence, they were ordered to bypass the original objectives, and move towards Adrano town, on the slopes of Mt. Etna.
The 15th Panzergrenadiers managed to scramble across the 7th Army to link up with other German units in the east. Hence, Patton was ordered to move north and cutoff the North Coast Road. He would then proceed to mop up the western side of the Island. Provisional Corps were to do the mop-up tasks, and 2nd Corps (both were under Patton) was ordered to move North.
On the 22nd of July, Patton's Provisional Corps entered the town of Palermo after mopping up, and on the 23rd, the 45th Infantry captured the North Coast road.
------------------------------------------------------------------------------------------------------
After Palermo, the objective was Mount Etna. Montgomery wished to take the town of Adrano, which would split the Germans in two on either side of the ridge. In the last week of July, the Canadians managed to capture Agira, almost 24 km west of Adrano. On the night of 1st August, they made a beeline for the isolated pinnacle of Centuripe, the main outpost of Adrano's southern defenses. Centuripe was secured by midday, 3rd August. At this juncture, Patton pushed the 45th Division up the east coast, and relieved it with the fresher 3rd division. He pushed the 1st Division up Route 120, and called up the 9th from reserves in Africa to relieve them.
Axis forces were now settled on a second defensive line, called the Etna Line. On 31st July, the 1st Division with attached elements from the reinforcing 9th Division entered Troina. This position was strategically important, and was held by the 15th Panzergrenadier, and remnants of the Aosta 28th Infantry, formed into four battalions. This battle continued for six days, with much casualties being inflicted upon the defenders as well as the attackers. By 7th August, the US 18th Infantry captured Mt. Pellegrino, thus allowing accurate artillery fire on Troina. Their left flank was exposed as the Hermann Goring Panzer Div. was being pushed behind by the XXX corps, and hence they withdrew that night.
In the meanwhile, XIII Corps captured Catania by the 5th of August, and Adrano fell to the 78th Infantry on 7th August.
Full scale withdrawal of the Axis forces began on 11th July, and continued till the 17th. Rear flanks kept the Allies occupied as their comrades escaped. Mines, roadblocks and barb wiring was extensively used in this incident.

Operation Husky: Opening of the offensive

[Note: Seaborne landings will be covered in this post. Airborne and Commando raids would be documented separately]
The seaborne landings were initially thrown off-course due to the strong winds, but the element of surprise was maintained because none of the defenders was expecting an attack in those conditions. The landings began in the early hours of 10 June along a 169-km long coastline, with the British and Canadians landing on the eastern tip, whereas Americans landed on the Western. Trouble experienced was from offshore sandbanks and weather conditions instead of the Axis armies. Some units landed on the wrong beaches altogether. But due to the poor quality of defensive operations, Allies were able to make up for lost time.

Once the Axis commanders took stock of the situation, the Allies began to meet resistance. The US 1st Infantry in Gela was attacked by an Italian mountain division. The Hermann Goring Panzer Div., which was due to advance along with them had failed to turn up at the place which was supposed to be the landing zone of the British 505th Para. During afternoon, artillery shelling from the USS Boise and the USS Shubrick slowed down the armored support due to reach the Gela beachhead. The infantry accompanying them was subsequently dispersed.

By evening, 3 American, 3 British, and one Canadian infantry division was well established on the shor, and Syracuse port had been captured largely intact. Fear of an air onslaught by the Axis air forces was nullified. Allied aircraft operating from Malta and the surrounding regions kept attacks at bay. Unfortunately however, attacks on the day of invasion were successful. Italian and Luftwaffe bombers sank a minesweeper, a hospital ship and a destroyer. In the following days, many more such ships were sunk by Stukas and Italian planes.

Operation Husky: Planning and preliminary offensives

PLANNING AND DISTRIBUTION OF FORCES
After routing out the Afrika Korps, the only logic would mean striking into south Europe from north Africa to open up the Mediterranean Sea for shipping. The natural choice would be Sicily. The plan was to have two armies, one at the south-eastern tip of the island, and other at the southern coast. These armies were to receive support from naval gunfire, as well as close air support. The Eastern Task Force (Force 545) consisted of the British 8th Army was led by Gen. Montgomery, whereas the Western Task Force (343) was commanded by Lt. Gen. Patton, consisting of the US 7th Army. Both reported to General Harold Alexander, commander of the 15th Army Group.

Patton group consisted of 3 Infantry Divisions, the U.S. 1st and 3rd, to be launched from Tunisia, and the U.S. 45th Div., to be launched form Algeria. Additionally, the US 2nd Armored div. was to be held as a mobile reserve, and would be induced into combat as required.
Monty group consisted of 4 Infantry Divisions and one independent brigade, organized into the XIII Corps, commanded by Gen. Miles Dempsey. The 231st Infantry was assigned the port of Suez as a launch-pad, whereas the UK 51st Division sailed from Tunisia and Malta. The 1st Canadian division, a new addition to the Corps, sailed in directly from the UK.

In addition to the Amphibious landings, airborne divisions as well as some British commandos were to be flown in to secure key bridges and high ground. This mission was undertaken by the British 1st Airborne, whereas the US 82nd Airborne was held as a reserve, under command of Maj. Gen. Matthew Ridgeway.
----------------------------------------------------------------------------------------------------------------------------
The Allied navies had also been grouped into two forces for the invasion. The Eastern Naval Task Force had been formed from the British Mediterranean fleet, and commanded by Adm. Bertram Ramsey.

This Corps consisted of the US 9th Air Force, 12th Air Force, and RAF squadrons which provided major air support. Even the Malta Air Corps HQ provided valuable support.

PRELIMINARY OFFENSIVES
The Allied Strategic bomber force began attacking major airfields in Sardinia, Sicily, and generally South Italy, Industrial targets in Italy and the major ports like Messina, Naples, and ports of Sardinia were also targeted. The idea was to maintain uncertainty as to where the invading forces would land. By the 10th of July, only two airfields remained intact in Sicily. Most Axis aircraft had been moved onto the mainland. Airmen flew almost 42,000 sorties over the region in the days leading up to the landing.
I have written about Opn. Mincemeat ((Refer: http://varunpendse.blogspot.in/2013/07/last-night-i-dreamed-deadly-dream.html ))
earlier in the blog, which was a deception plan attached to Opn. Husky. A corpse with documents chained to his body was let into the Spanish coast, which portrayed Greece as the target of the landings. These letters were written by the top brass themselves, and hence signatures were found to be authentic documents.

Operation Ambassador

Operation Ambassador was another of the first British Commando operations. In similarity with Opn. Colossus, there were no immediate military gains, but the experience derived from this raid helped subsequent raids.
The Wehrmacht had occupied the islands situated in the English Channel. British Prime Minister Winston Churchill thought that the newly formed British Commandos would be suitable for a raid and subsequent control of these islands. The raiding party consisted of 140 men in total. 100 men from No. 11 Independent Company under Maj. John Slater, and 40 men from No.3 Commando under Maj. Ronnie Todd.
The raid had been scheduled for the night of 12-13 July, but was postponed to 14-15 July. On 1745 hrs, the raiding party boarded two RN Destroyers along with six High-speed motor launches to ferry them to the island.
Like mentioned before, the operation was a failure. Under Maj. John's plan, the Independent companies would attack the airfield while the Commandos would create a diversion. But unfortunately, one launch landed up on entirely the wrong island due to a faulty compass, two launches broke down in the middle of the sea.
The Commandos reached the shore, soaking wet though. They discovered barracks and a few machine gun nests, but they had been abandoned long before. As the Destroyers were scheduled for pickup at 0300 hrs, and had orders to leave the soldiers behind in case of a delay, the commandos returned to the beach. The only inflicted damage was a cut telephone line. They found that they had to swim out to the boats almost 100m from the beach, and it was discovered that 3 of the men couldn't swim, and were left behind with additional French currency. During evacuation, a dinghy ferrying weapons from the beach again crashed into a rock, killing the pilot and two escorts. Slater suggested sending a submarine to get the three men, but they'd surrendered, and the Admiralty declined.
After the conclusion of the operation, it's planning quality and conduct has been called into question. As mentioned earlier, most of the equipment was not serviceable (compass, motor launches) or inadequate for the job. Some tasks assigned were impractical and not been practiced beforehand, eg. the wire intended to be used as a roadblock was too heavy to be carried from the beach.
On the political side, the raid was a disaster. Churchill was furious at the comical progress and outcome of the raid. It was being circulated that the entire commando concept was in Jeopardy.
The Independent Coy.'s were disbanded, and the first 12 Commando Battalions were raised out of them. Almost the full year they spent only in training. The successes of the Commandos in future operations such as Overlord were due to the expertise gained from the first failures.
