In response to protests from other senior officers that something was amiss as proven by the loss of the entire supply ship network in early 1941, in the middle of 1941 and again in the middle of 1942, Raeder ordered investigations into the security of German codes, but in both cases, it was concluded that the British were not reading German codes because the Enigma machine was considered to be unbreakable.

Raeder's strong authoritarian tendencies came to the fore as soon he assumed command of the Reichsmarine in 1928 when he sent out a circular making clear that dissent would not be allowed while at the same time carrying out the " great seal hunt " of 1928-29 when Raeder forced most of the senior admirals into early retirement in order to promote men who were loyal to him.

Right from the beginning when he assumed command of the Reichsmarine in 1928, Raeder waged a skilful public relations battle highly reminiscent of and closely modelled after the campaigns of Tirpitz in the early 20th century to convince both the politicians and the German public of the importance of sea power to Germany's future greatness.

Given his fears of the Communists, Raeder welcomed the rise of the NSDAP in the early 1930s as a counter-weight to the KPD.

Raeder used his old college Magnus von Levetzow, who worked as Adolf Hitler's naval adviser in the late 1920s and early 1930s to leak Reichsmarine material to the Nazis out of hope that this might win the Nazis over to navalism.

In the early 1930s, Raeder fought hard for increased naval budgets, lobbying politicians incessantly to argue that a strong navy was the prerequisite for Germany to become a world power.

Such was the degree of Raeder's lobbying for bigger naval budgets that in early 1932, General Kurt von Schleicher, who viewed Raeder as a threat to the Army budget attempted to discredit Raeder by leaking a story in the press that Raeder was plotting to be defence minister.

As part of the reorganization of the military command structure following the Blomberg – Fritsch Affair in early 1938, it was declared that the service chiefs, namely OKW chief Wilhelm Keitel, Army commander Walter von Brauchitsch, Luftwaffe commander Hermann Göring and Raeder were to have the same status as Cabinet ministers and as such, they all started to receive publicly the same pay as a Cabinet member and privately payments from Konto 5 slush fund.

When Britain and France declared war on Germany on 3 September 1939, Raeder was shocked and shattered by the outbreak of a general war that for the Kriegsmarine was at least five years too early.

In a message sent to all officers in early 1940, Raeder exclaimed: " The great aim of the Führer has set forth for the German nation requires the utmost exertion in all places ... A navy which undertakes daring actions against the enemy and suffers losses through this will be reborn on an even larger scale.

In a speech in early January 1943, Raeder called World War II an ideological war, praised National Socialism for its " moral strength ", and claimed that only through National Socialist indoctrination could the war be won.

The desire to use Norway as a base for naval attacks on Britain was the primary reason that motivated Raeder to advocate attacking Norway, and only in early 1940 did Raeder first mention protecting the sea lanes that allowed Swedish iron ore to reach Germany as a secondary reason for occupying Norway.

For a short period of time in early January 1940, the German Naval Staff managed to convince Raeder that the "' best ' solution was preservation of the status quo.

Admiral Conrad Patzig commented about Raeder in early 1940: " Raeder is strongly influenced by his surroundings and exceptional circumstances and under stress is impulsive and unpredictable if his pride and vanity are involved ".

Since in early July 1940 it was believed by both Hitler and Raeder that Britain would soon surrender, the decision to resume the Z Plan, which meant spending hundreds of millions of Reichsmarks building warships that would take at least five years to finish, reflected plans for an ultimate war with the United States.

By early 1942, Raeder and Dönitz were openly feuding with each other, with Dönitz mocking Raeder's obsession with " dinosaurs ", as Dönitz called battleships, and Raeder complaining of Dönitz's massive ego and his tendency to run the U-boat arm as it were his own private navy.

In early 1956, the City of Kiel decided to publicly give back to Raeder the Ehrenbürger (" free citizen ") status which the Nazis had awarded him and which been taken away by the British in 1945 ; after attracting much negative media attention all over the world, Raeder was secretly asked by the city government to decline the award.
