The Plan
For the assault to install democracy on the Soviet Union, the United Kingdom had amassed the equivalent of eleven armies, split between five army groups, within Europe all the under the direct command of Field Marshal Brook; the Chief of the Imperial General Staff. To protect the only remaining Far East Asian colony, Burma, the Fourteenth Army had been assembled out of the remains of what use to be the Indian Army.
Brooke’s plan relied heavily on intelligence from the Secret Intelligence Service coupled with the idea of a three pronged attack as enacted by the Germans. The SIS had informed the military that the Soviet Red Army contained around 3 million men with the vast majority deployed in the East; although it was believed the Red Army could be even larger in the region of 4 million, double our own force. On the “western front” 37 divisions had been identified within the former Baltic States, around 25 divisions in the centre and only roughly 20 divisions identified facing the line to be occupied by the British Fifth, Eighth and Ninth Armies.
This intelligence gave the impression that a quick strike, if it broke through the crust of the Soviet defences, would be able to advance almost unopposed into the interior of the USSR as reinforcements from the east would arrive too late to halt the advance. Each army group was assigned specific tasks to ensure the complete destruction of the Red Army but to gain the necessary jumping off points to achieve the overall objective of securing a 1,500 mile lone frontline stretching from the Arctic to the Caspian; in essence kicking communism out of Europe and beyond the Urals. On ‘D-Day’ 75% of British forces in Europe would cross along 500 miles of the Soviet border; 98 divisions with substantial artillery, aerial and armoured support would crush the Red Army.
21st Army Group (A), under the command of Field Marshal Montgomery, comprised the Sixth and Seventh Armies totalling 443,000 men and 3,200 tanks was given the objective of destroying the Soviet forces in the former Baltic States; to do so Sixth Army would spread out across the majority of the front and hold the line, Seventh Army would concentrate and unleash a colossal crack – punching through the frontline it would encircle the northern Soviet forces and open the gates to Leningrad.
11th Army Group (B) under the command of Field Marshal Alexander was assigned the Second, Third and Fifth Armies totalling 655,000 men and 4,800 tanks; Alexander’s goal was to encircle and destroy Soviet forces on the border and advance on a broad front into the Russian interior capturing Moscow.
15th Army Group (C), under Slim, also contained 443,000 men and 3,200 tanks. Given the apparent weakness of Soviet forces in the south much more ambitious goals were assigned to Slim. Eighth Army was given the task of providing flank protection to 11th Army Group while also ordered to move on Stalingrad. Ninth Army, would by itself, secure southern Ukraine encircling and destroying all opposition.
Held in reserve were the First and Fourth Armies of Messervy’s 18th Army Group and Mountbatten’s 200,000 strong Combined Operations Command aka the Airborne Army and the Royal Marines. 18th Army Group’s role was envisioned as slotting between Slim’s and Alexander’s forces when enough space opened up. The six marine divisions would be split between the north and the south aiding were needed and the airborne would be called upon if required although no task had yet been envisioned for them.
The 140,000 men of Burma Command were assigned a limited offensive role to shorten the frontline they would have to defend, other than that they had no role in Animal Farm.
The quality of the British divisions varies greatly, all are well trained however only a portion have seen combat; all Army Groups contain a mixture (bar First Army being most comprised of veteran units fresh from Japan and hence why they have been placed in reserve) however the best of the officer corps have been assigned to Alexander’s command. No other reserves were available nor were any forces assigned to protect the British Isles. Brooke’s plan was the all or nothing destruction of the Soviet Union.
