Following the outbreak of
World War II, Alexander, like all leading Labour figures, opposed forming a
coalition government under
Neville Chamberlain. Alexander firmly believed that
Winston Churchill should replace Chamberlain as Prime Minister. He worked with
Arthur Greenwood, and against
Herbert Morrison, who favoured
Lord Halifax as successor, to convince Attlee and the party's
Executive to support Churchill. In the closing days of April 1940, Churchill met with Alexander,
Clement Attlee and
Sir Archibald Sinclair to discuss the possibilities for a coalition government. Halifax's friend,
Chips Channon, described this as Churchill prematurely forming his cabinet in the expectation of becoming PM. Two weeks later, on 10 May, Churchill was Prime Minister of a coalition government; after forming his War Cabinet, which included Attlee and Greenwood, he invited Alexander and Sinclair (Air), along with
Anthony Eden (War, i.e. the Army), to head the three service ministries. Alexander returned to the Admiralty as First Lord, but like the other service ministers, was dominated by Churchill and existed very much in his shadow. It was a measure of Churchill's confidence in him that he was not given access to the secret information, nor was he allowed in the War Room. By appointing himself his own Minister of Defence, Churchill was well placed to exercise close supervision over the three services. An example was Churchill's decision to send
Force Z including the battleship and the battlecruiser to Singapore without, as it transpired, adequate air support. Both Alexander and the
First Sea Lord,
Dudley Pound had vigorously opposed this deployment but were overruled by Churchill. This decision was made before
Pearl Harbor – the ships were sent east as a deterrent to Japanese aggression, at the request of the Australian government and British forces in the Far East. Initially an aircraft carrier
HMS Indomitable was included, but she ran aground in the Caribbean, and was not replaced by
HMS Hermes which was regarded as too slow.
Prince of Wales and
Repulse were
attacked and sunk by Japanese aircraft off the Malayan coast immediately after the Pearl Harbor attack, before plans for their re-deployment in the light of actual hostilities with the Japanese could be decided upon and executed. Although Churchill had overall responsibility for the deployment, according to Richard Lamb, he 'had no responsibility for the fate of these two battleships'. The Admiralty view, argued for by Alexander and Pound, was that the
Prince of Wales and the
Repulse would have been better deployed in the Atlantic to counter the German threat from the German battleships
Tirpitz, the
Scharnhorst and the
Gneisenau. Alexander performed his duties with energy and diligence. He was committed to the administrative duties of his role, often sleeping in his office, but also took a keen interest in the welfare of sailors. He joined an
Arctic Convoy in 1942, and visited troops a few days after
D-Day in 1944, the first British minister in France since the occupation in 1940. His radio broadcasts and public appearance boosted morale and made him very popular inside and outside the service. As a working-class politician in a top position, he was an important figure for national unity. He had regular meetings with Churchill when in London, acting as an advisor; they were good friends and Churchill arranged for Alexander to receive an
Honorary Degree from the
University of Bristol, of which Churchill was Chancellor. However, Alexander firmly supported Labour's withdrawal from the coalition in May 1945, following victory in
Europe. Campaigning in the
election in July, he drew a sharp distinction between Churchill and the Conservative Party, suggesting that the Tories would sideline the wartime leader as they had done
Lloyd George in
1922. A member of the Cabinet following Labour's victory, Alexander strongly supported the
Foreign Secretary,
Ernest Bevin, sharing his goals of maintaining Britain's influence and opposing the
Soviet Union. Britain's wartime ally was admired at the time, and his outspoken criticisms of Russia lessened Alexander's popularity. In 1946 he deputised for Bevin at the
Paris Peace Conference, and was part of the Cabinet delegation to
India, under
Stafford Cripps, exploring possibilities for independence. At the end of 1946 he became Minister of Defence, a role previously held only by Churchill and Attlee when they were serving as Prime Minister. Responsible for all three armed services, he often clashed with the
Chief of the Imperial General Staff,
Lord Montgomery. He was responsible for formulating the system of
national service and faced a protracted fight against Labour backbenchers who opposed the continuation of
conscription in peacetime. In January 1947 he was one of six ministers on the
Gen 75 Committee that secretly authorised Britain's
nuclear programme; in March he was in the negotiations for the
Treaty of Dunkirk, laying the foundations for
NATO. As the
Cold War began, Alexander's criticisms of the USSR gained wider acceptance. In 1948 he became a
Freeman of the City of
Sheffield. ==Leader in the Lords==
