Question: In what real life city was the novel "U-96" based in 1941?
About the article "Das Boot", section "Historical accuracy".

Candidate passages:
In the film, there is only one ardent Nazi in the crew of 40, namely the First Watch Officer (referred to comically in one scene as "Unser Hitlerjugendführer", "Our Hitler Youth Leader"), with the rest of the officers either indifferent or, in the Captain's case, openly cynical.
The enlisted sailors and non-commissioned officers are portrayed as apolitical.
In his book "Iron Coffins", former U-boat commander Herbert A. Werner states that the selection of naval personnel based on their loyalty to the party occurred only later in the war (from 1943 onward), when the U-boats were suffering high casualties.
At that stage in the war, morale was surely declining and this degree of skepticism may have occurred.
In support of "Das Boot" on this subject, U-Boat historian Michael Gannon maintains that the U-boat navy was one of the least pro-Nazi branches of the German armed forces.
Even though the beginning and the end of the film occur in the port of La Rochelle, it does not correspond historically.
The submarine base in La Rochelle was not functional before November 1941, and at the time of the film the port was dried up.
Moreover, none of the British fighter-bombers of late 1941 to early 1942 had the range to bomb La Rochelle from bases in the U.K.; however, it is possible the fighters were carrier-based and not land based.
While Saint-Nazaire was the base used in the novel, the film was changed to La Rochelle because its appearance had not changed to such a large degree in the years since World War II.
In real life, the "U-96" was based at Saint-Nazaire in late 1941.
It survived this period, but much like its on-screen fate, it actually was sunk by Allied bombers at its berth in Wilhelmshaven in March 1945.
German submarine "U-96" was a Type VIIC U-boat of the German Navy ("Kriegsmarine") during World War II.
Her keel was laid down on 16 September 1939, by Germaniawerft, of Kiel as "Werft-Nummer 601".
She was commissioned on 14 September 1940, with "Kapitänleutnant" Heinrich Lehmann-Willenbrock in command.
Lehmann-Willenbrock was relieved in March 1942 by "Oberleutnant zur See" Hans-Jürgen Hellriegel.
He was relieved in turn in March 1943 by "Oblt.z.S.".
Wilhelm Peters.
In February 1944, "Oblt.z.S."
Horst Willner took command, turning the boat over to "Oblt.z.S."
Robert Rix in June of that year.
Rix commanded the boat until February 1945.
As part of the 7th U-boat Flotilla, stationed in Saint Nazaire, on the French Atlantic coast, "U-96" conducted 11 patrols, sinking 27 ships totalling and damaging four others totalling 33,043 GRT.
She also caused one vessel of 8,888 GRT to be declared a total loss.
The boat was a member of eleven wolfpacks.
On 30 March 1945, "U-96" was sunk by US bombs while in the submarine pens in Wilhelmshaven.
In her entire career, she suffered no casualties to her crew.
The boat was also known for its emblem, a green laughing sawfish.
It became the symbol of the 9th Flotilla after Lehmann-Willenbrock took command in March 1942.
During 1941, war correspondent Lothar-Günther Buchheim joined "U-96" for a single patrol.
His orders were to photograph and describe the U-boat in action for propaganda purposes.
Over 5,000 photographs, mostly taken by Buchheim, survived the war.
From his experiences, he wrote a short story, ""Die Eichenlaubfahrt"" ("The Oak-Leaves Patrol") and a 1973 novel which was to become an international best-seller, "Das Boot", followed in 1976 by "U-Boot-Krieg" ("U-Boat War"), a nonfiction chronicle of the voyage.
In 1981 Wolfgang Petersen brought the novel to the big screen with the critically acclaimed, "Das Boot". 
The novel tells the story of Porgy, a crippled street-beggar in the black tenements of Charleston, South Carolina, in the 1920s.
The character was based on the real-life Charlestonian Samuel Smalls.
Some passages in the novel have the characters speaking in the Gullah language. 
For her second foray, "U-96" departed Lorient on 9 January 1941 and returned to the waters west of Scotland, sinking the on 16 January and the a day later.
The "Almeda Star" was lost with all hands and passengers, a total of 360 people.
"U-96" docked once more in Lorient on the 22nd.
