45th Infantry Division (United Kingdom)

Infantry division of the British Army
the unrelated [[World War I

The 45th Infantry Division was an infantry division of the British Army, formed just prior to the start of the Second World War. In March 1939, after the re emergence of Germany as a significant military power and its occupation of Czechoslovakia, the British Army increased the number of divisions in the Territorial Army (TA) by duplicating existing units. The 45th started forming in August 1939 and became active the following month, as a second line duplicate of the 43rd (Wessex) Infantry Division. The division's battalions were all raised in the West Country. It was intended that the division would remain in the United Kingdom to complete training and preparation, before being deployed to France within twelve months of the war breaking out. Instead, the division was largely dispersed in order to protect strategically important points. As a result of the rapid German victory on mainland Europe during the Battle of France in 1940, the division was not deployed overseas and was instead dispatched to Sussex to defend the coast from a potential German invasion. This mission was extended to cover sections of the Kent coastline, and was followed by stints defending Essex and being held back from the coast as a counter attack formation. In December 1941, the division was earmarked to remain within the UK and not be deployed overseas as a combat formation. This was followed by further periods of coastal defence, and training in Northern Ireland. In 1944, the division's manpower was slowly transferred away as it was used to reinforce combat formations within the 21st Army Group, and the division was disbanded in August 1944. The division was reformed in September as the 45th (Holding) Division, composed of personnel from the disbanded 77th (Holding) Division. In this capacity the division was responsible for retraining soldiers on medical leave or who had spent a large amount of time overseas or as prisoners of war and assigning soldiers to new units. In December 1945, the division was renamed the 45th Division. Shortly after, it had three new brigades attached, all with the function of helping with the influx of returning soldiers from overseas deployment. As part of the demobilisation of the British armed forces after the Second World War, the division ceased to exist by the end of 1945 and has not been reformed.

During the 1930s, tensions increased between Germany and the United Kingdom and its allies. In late 1937 and throughout 1938, German demands for the annexation of Sudetenland in Czechoslovakia led to an international crisis. To avoid war, the British Prime Minister Neville Chamberlain met with German Chancellor Adolf Hitler in September and brokered the Munich Agreement. The agreement averted a war and allowed Germany to annexe the Sudetenland. Although Chamberlain had intended the agreement to lead to further peaceful resolution of issues, relations between both countries soon deteriorated. On 15 March 1939, Germany breached the terms of the agreement by invading and occupying the remnants of the Czech state. On 29 March, British Secretary of State for War Leslie Hore Belisha announced plans to increase the part time Territorial Army (TA) from 130,000 to 340,000 men and double the number of TA divisions. The plan was for existing TA divisions, referred to as the first line, to recruit over their allowed complements (aided by an increase in pay for Territorials, the removal of restrictions on promotion which had hindered recruiting, construction of better quality barracks and an increase in supper rations) and then form a new division, known as the second line, from cadres around which the divisions could be expanded. This process was dubbed "duplicating". The 45th Division was to be a second line unit, a duplicate of the first line 43rd (Wessex) Infantry Division. It was envisioned that the duplicating process and recruiting the required numbers of men would take no more than six months. Some TA divisions had made little progress by the time the Second World War began; others were able to complete this work within a matter of weeks. In April, limited conscription was introduced. This resulted in 34,500 twenty year old men being conscripted into the regular army, initially to be trained for six months before deployment to the forming second line units.

On 28 August 1939, the embryo of the division was formed. Major General Frederick Witts, formally a staff officer in the British Indian Army's Western Command with experience commanding an infantry brigade, was assigned as the General Officer Commanding (GOC). It was not until 7 September that the 45th Infantry Division became active. At that point, it took control of the 134th, 135th, and 136th Infantry Brigades, in addition to supporting divisional units, which had previously been administered by the 43rd (Wessex) Infantry Division. Due to the lack of official guidance, the newly formed units were at liberty to choose numbers, styles, and titles. The division adopted the number, but not the title, of their First World War counterpart, the 45th (2nd Wessex) Division; furthermore, the battalions that made up the division were largely unrelated to their parent unit. The 134th Brigade initially consisted of the 4th, the 6th, and the 8th Battalions, Devonshire Regiment (DR); the 135th Infantry Brigade was made up of the 5th, the 6th, and the 7th Battalions, Somerset Light Infantry; and the 136th Brigade consisted of the 9th Battalion, DR, and the 4th and the 5th Battalions, Duke of Cornwall's Light Infantry. To denote the association of the division with the West Country, where the division's battalions were raised, its insignia referred to Devon born Sir Francis Drake's Drum: according to the Imperial War Museum, "A yellow drum, red bands top and bottom, white cords, a small red diamond above a dark blue half circle in the centre, all on a khaki ground." The division was assigned to Southern Command, and largely dispersed to guard strategically vital areas. It was envisioned that the TA divisions each be deployed intact to reinforce the British Expeditionary Force (BEF) in France as equipment became available, with all 26 TA divisions deployed by the end of the first year of the war. The deployment timetable called for waves being sent to France in the fourth, fifth, sixth, ninth, and twelfth months of the war. By February 1940, the 45th Division had been earmarked for the fourth contingent of TA divisions to be deployed. To do so, the division was to be concentrated to complete its training; a process that had thus far been complicated by having 2,600 of the division's troops assigned to guarding vulnerable points. In May 1940, due to the swift nature of the German operations on mainland Europe, Commander in Chief, Home Forces General Walter Kirke grew concerned over the threat posed by the Germans to South East England. As a result, the division was assigned to Eastern Command and deployed to Sussex to defend the coast. As a consequence of the German victory in the Battle of France and the return of the BEF following the Dunkirk evacuation, the division was not deployed overseas. On 25 May, the 135th Brigade (based at Romney Marsh) was temporarily attached to the 1st London Division. A British infantry division was allocated seventy two 25 pounder field guns. On 31 May, the division had 12 such modern guns, in addition to six First World War vintage 18 pounder field guns, and twelve howitzers of similar vintage. The division had only six anti tank guns, against a nominal establishment of 48, and only 154 of the required 307 Boys anti tank rifles. It had 590 Bren light machine guns, compared to an establishment of 644. In regards to Universal Carriers, it had 63 instead of the required 140, these were supplemented with a number of Humber Light Reconnaissance Cars. In June, a Home Guard memorandum described the division as consisting of "two weak Brigades [134th and 136th] disposed on the coast", with orders to "hold their positions 'to the last man and the last cartridge'", and supplemented by Home Guard volunteers "manning barricades consisting of tree trunks, old motor cars, farm carts and barbed wire trestles on the main approaches to towns and villages". British defensive thinking ideally called for a division to be deployed with two brigades forward, each with two battalions in coastal positions and the third positioned around 6 mile (10 km) inland to provide a counter attack force. The third brigade would be positioned further inland to provide an additional counter attacking force and in particular to retake airfields lost to German paratroopers. However, this layout was rare. With the return of the 135th Brigade on 10 July, the 45th Division was also given responsibility for coastal defence into Kent. From west to east, the 136th Brigade was based around the potential landing zones near Eastbourne, the 134th Brigade covered the coast between Bexhill on Sea and Hastings, and the 135th Brigade was responsible for the area between Rye and Dymchurch. The division was placed under the command of XII Corps. By September, the 2nd New Zealand Division had been placed behind the 45th Division, to counter attack any German force that assaulted the 45th Division's position. Assigned to I Corps in November, the division was moved off the south coast to Nottinghamshire. It was then placed directly under the command of Home Forces, and rotated between coastal defence duties in Essex and maintaining a position in the English hinterlands as a counter attack formation. In July, the division was placed under the command of XI Corps. In December, the division was placed on the lower establishment and was deployed to the Essex coastline in 1942. The TA was reformed in 1947 on a much smaller scale of nine divisions, which did not include the 45th.
