Dear Adolf Hitler, Fuhrer of the Third Reich:

We lost the battle in Moscow, the attacks to invade the Soviet Union have failed. As we were trying to invade the Soviet Union, our forces have been reduced. The operation seemed to work very well at the begging but we have lost every battle lately. It is known that our forces are reduced but germans fight fiercely, still we should retreat and hope to regroup the remaining forces. 

I must also inform the death of Generalfeldmarschall von Bock, as he was in the road to Kiel, he was reached by enemy fired. It is my sad duty to inform that von Bock was killed along his family. 

Fuhrer, after the failure in the Soviet Union, I'm no longer sure if the war will be won.

Awaiting your orders, Generalfeldmarschall von Brauchitsch

Dear Adolf Hitler, Fuhrer of the Third Reich:

I have done what you bid, I was meant to conquer Ukraine and so I did. The plan you traced didn't work as I hoped. The battle was hard, dear Fuhrer. You said that the Red Army would collapse and it didn't, I had to command my forces into what it will become one of the best victories in the history of warfare. 

Although we won Ukraine, the remaining soldiers are tired. Two months of continuous fighting are not easy. We have lost men and resources, I'm not completely sure this will be a quick victory as we planned Fuhrer. We will leave Kiev and go towards Stalingrad as soon as possible.

It is only natural that such great effort would result in fatigue, the combat strength of the troops has weakened and in many places there is a desire for rest. But, we must keep pressure on the enemy for he has many more reserves than we. 

 Always at your service, Generalfeldmarschall Rundstedt.

June 22nd, 1941

Dear Adolf Hitler, Fuhrer of the Third Reich

 Today is maybe one of the most important days in German history. Today we begin Operation Barbarossa. Barbarossa will be the largest operation and attack of World War II, and will mark the beginning of German rule in Russia. This plan, which you have constructed in December of 1940, doesn’t have any possibility of failing. The primary attack we’ll be given in the north. This way we convert Leningrad and Moscow in vital targets for invasion. As you said, when Barbarossa commences, the world will hold its breath and make no comment.

 I will be leading the North Army and face the Baltic Special Military District led by Kuznetsov. The Centre Army will be led by General von Bock and the South Army will be led by General von Rundstedt. We will attack by blitzkrieg (with light tanks and the support of planes and infantry). In total we have 117 army divisions, without considering Rumanian and Hungarian troops. As I have already told you, chances of failing are inexistent.

Yours sincerely,

General Wilhelm Ritter von Leeb

Introduction

Operation Barbarossa talks about the instantaneous invasion of Germany to Soviet Union during the Second World War (WW2), which was supposed to be defeated in an attack of only around two months. The last plan of Hitler was to proceed simultaneously with three military groups, that were supposed to move correctly with the aim of encircle or fence the soviet army. Adolf Hitler, also known as “the Fürher” named the operation “Barbarossa” in honor of Federic I and his beard’s color.

The idea of Adolf Hitler was to invade URSS with the aim of expand to the East with his thought of “living space”, although this was an old German idea of the First World War (WW1). As Hitler wrote on his book Mein Kampf (My Struggle), the war with the Soviet Union is a conflict between Europe and Asia: the idea was to eliminate and stop those Asians who make run the European and national-socialist “New Order”. As we already mention, the gained territory will convert into the “living space” which will satisfied the necessities of land and raw material for the German society for centuries.

The invasion was first scheduled for May 15, but Mussolini's intervention in East Africa against British Somalia and his abortive invasion of Greece during the winter of 1940 delay the operation, and in this situation Hitler declare the invasion of Greece (Operation Marita). Not enough, Hitler also sort the invasion of Yugoslavia as an answer of its coup.

In the midnight of Sunday 22 of June, in 1941, Germans start with more than 4 million people, with 4000 tanks and 4000 airplanes, making the most bigger and important operation in all history. At first the Soviet army was collapsed as all was planned. The Luftwaffe (German Air Force during Hitler’s period) in a little period of time destroyed the most important airplanes of the Soviet’s air force after they can take off.
