Planning The operation was initiated by
František Moravec, head of the Czechoslovak intelligence services, with the knowledge and approval of Beneš, almost as soon as Heydrich was appointed Protector. Moravec personally briefed
Brigadier Colin Gubbins, who at the time was the Director of Operations in the British
Special Operations Executive (SOE) and who had responsibility for the Czech and Polish "country" sections of the organisation. Gubbins readily agreed to help mount the operation, although knowledge of it was restricted to a few of the headquarters and training staff of SOE. The operation was given the
codename Anthropoid,
Greek for "having the form of a human", a term usually used in
zoology. Preparation began on 20 October 1941. Moravec had personally selected two dozen of the most promising personnel from among the 2,000 exiled Czechoslovak soldiers based in Britain. They were sent to one of SOE's
commando training centres at
Arisaig in Scotland.
Warrant Officer Jozef Gabčík (Slovak) and
Staff Sergeant Karel Svoboda (
cs) (Czech) were chosen to carry out the operation on 28 October 1941 (Czechoslovakia's Independence Day), but after Svoboda received a head injury during training he was replaced by
Jan Kubiš (Czech). This caused delays in the mission because Kubiš had not completed training, nor had the necessary false documents been prepared for him. Training was supervised by the nominal head of the Czech section, Major Alfgar Hesketh-Prichard, who turned to
Cecil Vandepeer Clarke to develop the necessary weapon. It was light enough to throw but still lethal enough to destroy an armour-plated
Mercedes-Benz. During extensive training, the new weapon was found to be easy to throw by Hesketh-Prichard (who had a strong
cricketing background,
his father having been a
first-class bowler), but less so by Gabčík and Kubiš.
Insertion Gabčík and Kubiš, along with seven other soldiers from Czechoslovakia's army-in-exile in the United Kingdom in two other groups,
Silver A and
Silver B (who had different missions), were flown from
RAF Tangmere by a
Halifax of
No. 138 Squadron RAF at 22:00 on 28 December 1941. The groups, along with some supply containers, left the plane by parachute, in drops in three separate areas. The Anthropoid pair landed near
Nehvizdy east of Prague. Originally, the plane had been planned to land near
Pilsen, but the aircrew had navigation problems and each of the groups landed in different places from where intended. Gabčík and Kubiš then moved to Pilsen to contact their allies, and from there on to Prague, where the attack was planned. In Prague, the pair contacted families and
Czechoslovak resistance organisations who helped them during the preparations for the assassination. Upon learning of the nature of the mission, resistance leaders begged the Czechoslovak government-in-exile to call off the attack, saying that "[a]n attempt against Heydrich's life... would be of no use to the Allies and its consequences for our people would be immeasurable". Beneš personally broadcast a message insisting that the attack go forward, although he denied any involvement after the war. Lawyer and diplomat
Vojtěch Mastný argued that Beneš "clung to the scheme as the last resort to dramatize Czech resistance".
Attack in Prague submachine gun. Gabčík's gun suffered from
failure to feed. Czechoslovak paratroopers often complained about the low reliability of British firearms. At 10:30 on Wednesday, 27 May 1942, Heydrich started his daily commute from his home in
Panenské Břežany, north of central Prague, to his headquarters at
Prague Castle. He was driven by SS-
Oberscharführer Johannes Klein. Gabčík and Kubiš waited at the tram stop at the junction between the road then known as , and , in
Prague 8-
Libeň near
Bulovka Hospital. The tight curve there would force Heydrich's car to slow down as it turned westwards into .
Josef Valčík (from group
Silver A) was positioned about north of Gabčík and Kubiš to look out for the approaching car. Heydrich's green, open-topped
Mercedes 320 Cabriolet B reached the curve two minutes later. Gabčík concealed his
Sten submachine gun under a raincoat. As the car slowed and rounded the corner, Gabčík dropped his raincoat and raised the gun to shoot Heydrich but the gun
jammed. Heydrich stood up and drew his
Luger pistol, yelling to halt instead of ordering to accelerate. As the car braked in front of him, Kubiš, who was not spotted, threw a modified
No. 73 grenade (concealed in a briefcase) at the car; he misjudged his throw. Instead of landing inside the car, it landed against the rear wheel. Nonetheless, the bomb severely wounded Heydrich when it detonated, its
fragments ripping through the right rear fender and embedding fragmentation and fibers from the upholstery of the car into Heydrich, causing serious injuries to his left side, with major damage to his
diaphragm,
spleen and
lung, as well as fracturing a rib. Kubiš received a minor wound to his face from the shrapnel. The explosion shattered the windows of the tram which had stopped on the opposite side of the road, shrapnel striking passengers. Two SS jackets folded on the back seat of the car were whirled upwards by the blast and draped themselves over the trolley wire. Heydrich and Klein leapt out of the shattered Mercedes with drawn pistols; Klein ran towards Kubiš, who had staggered against the railings, while Heydrich went to Gabčík, who stood holding the Sten. Kubiš recovered, jumped on his bicycle and pedaled away, scattering passengers spilling from the tram by firing in the air with his
Colt M1903 pistol. Klein tried to shoot at him, but dazed by the explosion, pressed the magazine release catch and the gun jammed. A staggering Heydrich came towards Gabčík, who dropped his Sten and tried to reach his bicycle but was forced to abandon the attempt and took cover behind a
telegraph pole, firing at Heydrich with his pistol. Heydrich returned fire and ducked behind the stalled tram, when he suddenly doubled over and staggered to the side of the road in pain. He then collapsed against the railings, holding himself up with one hand. As Gabčík took the opportunity to run, Klein rushed to help his superior. Heydrich, his face pale and contorted in pain, pointed toward the fleeing Gabčík, saying, "Get that bastard!" As Klein gave pursuit, Heydrich stumbled along the pavement before collapsing against the bonnet of his wrecked car. Gabčík fled into a butcher shop, where the owner, a man named Brauer, who was a Nazi sympathiser and had a brother who worked for the
Gestapo, ignored his request for help. Brauer ran out to the street and attracted Klein's attention by shouting and pointing to the shop. Klein, whose gun was still jammed, ran into the shop and collided with Gabčík in the doorway. In the confusion, Gabčík shot him twice, severely wounding him in the leg. Gabčík then escaped in a tram, reaching a local
safe house. At this point, Gabčík and Kubiš did not know that Heydrich was wounded and thought the attack had failed.
Medical treatment and death A Czech woman and an off-duty policeman went to Heydrich's aid and flagged down a delivery van. Heydrich was first placed in the driver's cab but complained that the truck's movement was causing him pain. He was then transferred to the back of the truck on his stomach and taken to the
emergency room at Bulovka Hospital. A Dr. Slanina packed the chest wound, while Walter Dick, the
Sudeten German chief of surgery at the hospital, tried to remove the shrapnel splinters. Josef Hohlbaum (a
Silesian German who was chairman of surgery at
Charles University in Prague) operated on Heydrich with Dick and Slanina's assistance. The surgeons reinflated the collapsed left lung, removed the tip of the fractured 11th rib,
sutured the torn diaphragm, inserted several
catheters and removed the spleen, which contained a grenade fragment and upholstery. The world is just a barrel-organ which the Lord God turns Himself. We all have to dance to the tune which is already on the drum. Heydrich's fever and drainage subsided and his condition appeared to be improving until, while sitting up eating a noon meal on 3 June, he suddenly went into
shock. Another suggestion was that Heydrich died of a massive
pulmonary embolism (and possibly a
fat embolism). In support of the latter possibility, particles of fat and blood clots were found at autopsy in the
right ventricle and
pulmonary artery and severe
oedema was noted in the upper lobe(s) of the lungs, while the lower lobes were
collapsed. The evidence cited to support the hypothesis includes the modifications made to the No. 73 grenade, the bottom two-thirds of this weapon had been removed, and the open end and sides were wrapped up with adhesive tape. The modification of the weapon could indicate an attached toxic or
biological agent. Heydrich received excellent medical care by the standards of the time. His
post mortem examination showed none of the usual signs of sepsis, although infection of the wound and areas surrounding the lungs and heart was reported. The botulinum toxin theory has not found widespread acceptance among scholars. Fildes had a reputation for "extravagant boasts", and the grenade modifications could have been aimed at making the weapon lighter. ==Consequences==
