Meanwhile, Tresckow also worked tirelessly to persuade army commanders such as Field Marshals Fedor von Bock, Günther von Kluge, and Erich von Manstein to join in the conspiracy without much success.

At that time Count Siegfried von Eulenberg, the commander of the 1st Regiment of Foot Guards, predicted that " You, Tresckow, will either become chief of the General Staff or die on the scaffold as a rebel.

General von Bock advised Tresckow to seek his support, but there is no evidence that he did so.

German Army ( Heer ) officers General Friedrich Olbricht, Major General Henning von Tresckow, and Colonel Claus von Stauffenberg modified the plan with the intention of using it to take control of German cities, disarm the SS, and arrest the Nazi leadership once Hitler had been assassinated in the July 20 Plot.

In September 1943, Goerdeler attended a meeting at the home of Olbricht where together with his host Olbricht, General Beck and von Tresckow he finally won over the vacillating Field Marshal Kluge into joining the conspiracy.

In 1934, Tresckow began General Staff training at the War Academy and graduated as the best of the class of 1936.

To gain access to Hitler, Tresckow proposed to his old comrade General Rudolf Schmundt, Hitler's Chief Adjutant and Chief of Army Personnel, to create a new department of psychological and political warfare to evaluate data and make reports directly to the Führer.

The name was coined by General Henning von Tresckow, who believed that only after a ' spark ' ( Hitler's death ) would other wavering collaborators agree to launch an internal coup d ' état to stop the war.

Though Adolf Hitler succeeded in garnering the support of many German industrialists, prominent traditionalists openly and secretly opposed his policies of euthanasia, genocide, and attacks on organized religion, including Claus von Stauffenberg, Dietrich Bonhoeffer, Henning von Tresckow, Bishop Clemens August Graf von Galen, and the monarchist Carl Friedrich Goerdeler.

Major-General Henning von Tresckow, one of the primary conspirators in the July 20 plot to assassinate Adolf Hitler, famously referred to the ' Robe of Nessus ' following the realization that the assassination plot had failed and that he and others involved in the conspiracy would lose their lives as a result: " None of us can complain about our own deaths.

Herrmann Karl Robert " Henning " von Tresckow ( January 10, 1901 – July 21, 1944 ) was a Generalmajor in the German Wehrmacht who organized German resistance against Adolf Hitler.

But by the beginning of September 1943, after a somewhat slow recovery from his wounds, he was propositioned by the conspirators and was introduced to Henning von Tresckow as a staff officer to the headquarters of the Ersatzheer (" Replacement Army " – charged with training soldiers to reinforce first line divisions at the front ), located on the Bendlerstrasse ( later Stauffenbergstrasse ) in Berlin.

In 1942, a new conspiratorial group formed, led by Colonel Henning von Tresckow, a member of Field Marshal Fedor von Bock's staff, who commanded Army Group Centre in Operation Barbarossa.

Tresckow systematically recruited oppositionists to the Group ’ s staff, making it the nerve centre of the Army resistance.

In late 1942, Tresckow and Olbricht formulated a plan to assassinate Hitler and stage an overthrow during Hitler's visit to the headquarters of Army Group Centre at Smolensk in March 1943, by placing a bomb on his plane.

During 1943 Tresckow tried without success to recruit senior Army field commanders such as Field Marshal Erich von Manstein and Field Marshal Gerd von Rundstedt, to support a seizure of power.

Tresckow in particular worked on his Commander-in-Chief of Army Group Centre, Field Marshal Günther von Kluge to persuade him to move against Hitler and at times succeeded in gaining his consent, only to find him indecisive at the last minute.

The real movers were now more junior officers: Henning von Tresckow, chief of staff of Army Group Centre, Friedrich Olbricht, Chief of the Armed Forces Replacement Office, and Claus Schenk Graf von Stauffenberg, a member of the Replacement Army staff.

Their initial target was Manstein, now commanding Army Group Don, but he turned Tresckow down at a meeting in March 1943.

A leading figure of the German military resistance, Henning von Tresckow, served as his Chief of Staff of Army Group Centre.

He knew about Tresckow ’ s plan to shoot Hitler during a visit to Army Group Centre, having been informed by his former subordinate, Georg von Boeselager, who was now serving under Tresckow.

Tresckow was born in Magdeburg into a noble family from the Brandenburg region of Prussia with 300 years of military tradition that provided the Prussian Army with 21 generals.

After World War I, Tresckow stayed with the famed Infantry Regiment 9 Potsdam and took part in the suppression of the Spartacist movement in January 1919, but resigned from the Weimar Republic Reichswehr Army in 1920 in order to study law and economics.

As Chief of Staff of the 2nd Army Tresckow signed an order on 28 June 1944 to abduct Polish and Ukrainian children in the so called Heu Aktion ( Hay Action ).

Witzleben dissuaded Tresckow from resigning from the Army arguing that they would be needed when the day of reckoning came.

At the end of September 1941, Tresckow sent his special operations officer Schlabrendorff to Berlin to contact opposition groups and declare that the staff of Army Group Center was " prepared to do anything.

Under the initial plan, a group of officers were to shoot Hitler collectively at a signal in the officers ' mess during lunch but Kluge, Commander of Army Group Center who was informed about the plot, urged Tresckow not to carry it out saying, " For heaven's sake, don't do anything today!

In 1940, Blumentritt — as the Operations Officer of Army Group A ( again under von Rundstedt )— took part in the planning ( with von Manstein and Henning von Tresckow ) and execution of the invasion of France.

Nonetheless, Tresckow did spadework for the invasion plan of Czechoslovakia and after the outbreak of World War II served as chief of staff of the 228th Infantry Division during the invasion of Poland, earning the Iron Cross first class.

During August and September 1943, Tresckow took long sick leave in Berlin to draft the " revised " Valkyrie plan with fine details and precise timetables.

Ironically, Tresckow played a role in the adoption of the Manstein Plan, which proved to be so successful in the French campaign.

When Stauffenberg sent Tresckow a message through Lieutenant Heinrich Graf von Lehndorff-Steinort asking whether there was any reason for trying to assassinate Hitler given that no political purpose would be served, Tresckow's response was: " The assassination must be attempted, coûte que coûte the cost.

Joachim Fest, writing of Tresckow, says: " Even officers who were absolutely determined to stage a coup were troubled by the fact that everything they were contemplating would inevitably be seen by their troops as dereliction of duty, as irresponsible arrogance, and, worst, as capable of triggering a civil war.

" Tresckow assured the conspirators that he would act on the first available opportunity.

* Suicide Mission: On 11 March 1944, Captain Eberhard von Breitenbuch ( another Tresckow recruit ) volunteered to walk into Hitler's conference room and shoot the Führer at point blank range knowing that he himself would be killed by SS guards.
