Raising the division
On 18 May 1940, Acting Brigadier Archibald Bentley Beauman, CBE, DSO, who was based at Rouen, was ordered by Major-General de Fonblanque (General Officer Commanding Lines of Communication Troops) to strengthen his local defences. He formed a small mobile force, "Beauforce", consisting of Territorial infantry battalions that had been intended to protect lines of communication and undertake pioneer work. A second formation, called "Vicforce", was formed from five provisional battalions made up of troops who had been employed in various depots, together with reinforcement drafts that had recently arrived in France. This second brigade-sized unit was named after its first commander, Colonel C. E. Vicary.
Beauman placed these forces in a defensive position along the rivers Andelle and Béthune so as to defend Rouen and Dieppe from the east. A further force, known as "Digforce", was created by combining numerous companies of the Auxiliary Military Pioneer Corps into several battalions under Lieutenant Colonel J. B. H. Diggle. These troops were mainly reservists who were not fit enough to join their front line units and had been tasked with construction and labour in the rear areas.
On 29 May, these three formations were combined to form Beauman Division and Beauman himself was promoted to acting Major-General to command it. This was the only example of a British Army division being named after its commander since the Peninsular War. The use of the word "division" was to cause problems later, as it misled the French high command into thinking it was supported by artillery, engineers and signals in the same way as a regular division, rather than a collection of largely untrained troops armed only with light weapons. A plan to withdraw all the improvised forces was dropped at the request of General Georges, who said that such a course of action would have "an unfortunate effect on the French Army and the French people".
The "Beauman Line"
In the first days of June, Beauman Division continued to construct what defences it could along the 55 mile Andelle-Béthune line. On 6 June, it was reinforced by a further three battalions of infantry; some artillery and engineer units arrived in the following days. However, "A" Brigade was detached to assist the 51st (Highland) Infantry Division; (it became part of Arkforce, which was formed to cover the retirement of the Highlanders towards Le Havre). Some units of the 1st Armoured Division arrived in support, but remained under the orders of the French Tenth Army commander, General Altmayer. The difficulty of maintaining communications led General Beauman to issue orders that units would hold on "as long as any hope of successful resistance remained" and that "Brigade commanders will use their discretion as regards withdrawal".
At dawn on 8 June, the 5th and 7th Panzer divisions renewed their drive towards Rouen. The first German attacks were at Forges-les-Eaux and Sigy-en-Bray. At Forges, refugees prevented the planned blocking of roads and, when French tanks appeared, they were allowed to pass through. However, they had been captured by the Germans and once through the road blocks, attacked the British positions from the rear. The units of the division were pushed back and the line was penetrated in many places, despite the support of 1st Armoured Division on their left. Late in the afternoon, Syme's Battalion, only formed from depot troops in the previous week, held up 5th Panzer for several hours outside Rouen before being forced to retire. During the night, the remainder of the division retired across the Seine.
The fragmented remains of the division that had escaped across the Seine were withdrawn to reorganise. On 16 June, the Tenth Army ordered a general retirement with the eventual aim of establishing a defensive position on the Brittany peninsula; a policy opposed by both Brooke and the British Government. Beauman Division was therefore ordered to fall back on Cherbourg for evacuation; part of Operation Ariel. This was a relatively straightforward task as, unlike some other British formations, they were not in contact with the Germans; however, it did involve crossing the line of retreat of part of Tenth Army. Arriving at Cherbourg, the division embarked on to the waiting ships with whatever equipment they had; the whole formation had been evacuated by 17 June. On arrival in England, the division was dispersed; an entry in the London Gazette for 16 August 1940 says simply: "Colonel A B Beauman, CBE, DSO, relinquishes the acting rank of Major-General on ceasing to command a Division - 21st July 1940."
