Then do what I did. Get a couple of navigation charts for the area and look at those. Next, you can get tide and weather information from sailing instructions and notes by the NOAA (yes, I took a year's worth of courses on naval navigation). The historical convoy route from the US was reminisent of Columbus' voyage in reverse. They used a great circle route to south of the Azores (under Allied control) and then instead of going to North Africa in this scenario they would turn North and head to France. There is alot less U-boat activity on that route as but one advantage of it.
This area is little effected by the more massive storms of the North Atlantic due to it being in the doldrums.

The same as it historically was with them landing in North Africa, on D-Day, or anywhere else. They came ashore and took care of business.

The one division guarding this part of the coast is the 333rd Infantry. It's responsibility runs from about Lorient to St. Nazarie. This was the division that fought the commando raid on the later when the HMS Campbelton blew up the locks to prevent docking the Bismarck there.

The unit TO&E is:

Grenadier regs 679, 680, 681
Artillery reg 333
Auxiliary units numbered 333

It has no orgainc antiaircraft battalion. Its only air defense is the 2cm AA company in the antitank battalion.

Its home station is Wkr III. It was formed 14th wave in January 1941. All personnel are essentially draftees. The unit suffered periodic drafts of men sent to other divisions as replacements. These were replaced by new conscripts and often men of lower quality ratings.
This is not uncommon with the Germans. They saw this division as being in a quiet sector of France and unlikely to be engaged.


Yes. They would be able to defeat the one thinly spread German division. Taking Belle Ile and Quiberon gives them three small ports and a huge safe anchorage to deliver supplies to the troops ashore. Like at Normandy or, in the Pacific, the Allies can simply use landing craft to run much of their supplies ashore. They can also dock ships and use DUKW trucks to supplement this.
Bringing in pontoons to build additional docks or to use as lighters would also be an option.

There aren't that many German aircraft in the area. The only two units that are really a threat to naval traffic are KG 100 and Fleiger Fuhrer Atlantik with about 30 to 40 aircraft between them.

Overwhelmed at Salerno?!! They threw in the 16th Pz, 26th Pz, 29th PzGr, 15th PzGr, Hermann Göring Panzer among other units against three Allied infantry divisions supported by one brigade of British 7th Armored division. They lost and lost badly. 16th Panzer was on the landing beaches when the Allies came ashore. There was no preinvasion bombardment so the unit was intact. Yet, it was thrown out of its positions.
They had air parity as Salerno was at the edge of Allied land based fighter cover and the Allies had no carrier aircraft available.
The Italians were still in the war and their fleet was largely intact. But, it lacked fuel to move for the most part.

At Anzio they again managed to get better than a one to one ratio of troops surrounding that beachhead. The Allies had initially just two divisions ashore. They tried two major offensives to destroy that beachhead and both failed miserably.

Hardly. The Germans entered their 1942 summer offensive (the one AGS makes against Stalingrad and the Caucausus) in poor shape. Panzer divisions in the East have only one battalion of tanks on average except for those in AGS half of which have two and one has three. They were short nearly 250,000 men on establishment and only AGS had infantry divisions close to full strength. Most divisions had been cut down to two battalions per regiment from their establishment three (the Type 44 division didn't exist yet).
They had a severe shortage of both trucks and horses. To support AGS all divisions elsewhere were largely stripped of their transport to provide enough trucks to get three Grosstransportraum units for motor transport of supply in AGS.
Whether you think they were winning or losing is irrelevant. The Germans at the end of 1942 were in bad shape.

Sunk or damaged by what? U-boats will take time to get there. Even when they do there are just three or four battleships present with the same number of carriers out of well over 100 ships present. They are not anchored, and they are escorted.
As for the German surface fleet: Tirpitz is in Norway. Scharnhorst and Gneisenau are in Germany and undergoing repairs. Even if all three could go to sea they have to either traverse the North Sea then the Channel and then the Bay of Biscay to get to the fight, or they have to go into the Atlantic through the Iceland gap and then south to the Bay of Biscay. This means bringing several unrep ships along. It also means no escorts.
In either case this suggestion is simply ludicrious. There is no way the Germans could put three capital ships into the area whatsoever. They would be sunk enroute.

No, the Allies get ashore. They dig in and a temporary stalemate ensues for the next six or so months. There is heavy fighting periodically during this period. In the East the loss of units now fighting in France makes a 1943 come back for the Germans impossible. They are forced onto the defensive and lose more ground than historically.
In North Africa Rommel's forces are partially withdrawn and the reminant defeated. The Allied prisoner bag is much smaller than historical.
The French throw in with the Allies forcing the Germans to invade and take Vichy France pulling more troops West. The Vichy French fight so this invasion and conquest takes weeks and alot of troops to complete.
Italy is still threatened in the Med now that Axis forces are defeated in North Africa.
