Sunday, 28 December 1941

Operation ANTHROPOID was the successful SOE-sponsored Czech resistance operation to assassinate Reinhard Heydrich. Though Heydrich was not in the second rank of the Nazi leadership dominated by Goering, Goebbels, Bormann and Himmler, he was definitely in the third rank. Respected and feared by most of those above him, Heydrich commissioned the methodical extermination that became the Holocaust. Operation ANTHROPOID is also notorious as the trigger for the Nazis’ revenge: the razing and erasure of the villages of Lidice and Lezacky, their populations liquidated or deported to concentration camps.


In September 1941 Konstantin von Neurath, Reichsprotector of Bohemia and Moravia, was replaced by Reinhard Heydrich as Acting Reichsprotector. In 1939 von Neurath had instituted a repressive regime in Czechoslovakia, but by 1941 Hitler regarded him as insufficiently zealous. Heydrich instituted a systematic programme of terror, with the wholesale arrest of political and resistance figures, many of whom were summarily executed. Almost immediately the Czechoslovak government-in-exile commissioned SOE to mount a coup-de-main operation to assassinate Heydrich, the man they saw as the cause of their country’s misfortune. Cut off the new head, they believed, and the situation might improve. But they mistook von Neurath’s regime to be the pattern for Nazi rule, unaware that Heydrich was Nazism unalloyed.

The operation was initially planned for October 1941, an instant response to the terror. Two soldiers were selected from the Czech forces in exile, Karel Svoboda and Jozef Gabcik, but ANTHROPOID had to be postponed following Svoboda’s injury in training; it took several weeks to prepare his replacement, Jan Kubis, and to furnish him with appropriate documents.

The sortie

For the pilot and crew of Operation ANTHROPOID it is an unusual sortie. Operations to eastern Europe are still rare, even in the winter months. The Whitley’s range is constrained by its low cruising speed (and therefore by the hours of darkness over enemy territory), and by its small payload when flown with a full complement of additional fuel-tanks. It’s a moot point as to whether the RAF would have permitted the operation to go ahead in September or October 1941; in a Whitley it would almost certainly have been a one-way trip.

General Sikorski has relentlessly lobbied for a Polish Air Force Flight equipped with faster, long-range aircraft to make feasible regular air contact with the Polish homeland. The RAF has unbent sufficiently for 138 Squadron to have received its first Halifaxes. The squadron has been augmented with Polish and Czech aircrew. One operation (RUCTION) has already been carried out with a Polish crew, with a mixed result: the operation successful, the aircraft crash-landed in Sweden through aircrew error. F/Lt Ron Hockey has undergone Halifax conversion training with a new crew, the training provided at Linton by 35 Squadron, the first operational Halifax squadron. The Canadian pilot Richard Wilkin is Hockey’s 2nd Pilot. ANTHROPOID will be combined with operations SILVER A (a three-man team) and SILVER B (two agents), both of which have failed on earlier attempts.

Before mid-day, Hockey and crew fly to Northolt and back; they may or may not have landed at Northolt. There is no explanation for the flight in Hockey’s logbook; it may have been only an extended air-test for Hockey and his crew to check out the complex aircraft thoroughly.

Stradishall’s runways are too short for a fully-fuelled Halifax, so Hockey flies to Tangmere before taking off, fully-fuelled, from its extra-long runway at about 22.00. The Halifax has a crew of eight (the Halifax’s normal bomber crew of seven, plus a Despatcher), seven agents for the three operations, plus Major Sustr of SOE’s Czech Section as Accompanying Officer: a total of sixteen souls, plus two containers for ANTHROPOID. Hockey’s take-off run is about 1,300-1,400 yards into a 15 mph head-wind. The meticulous Hockey records his take-off weight as 59,800 lbs. He and his crew cross the French coast near Le Crotoy, at the mouth of the Somme estuary. He then sets course for the German town of Darmstadt, possibly because the Rhine has a distinctive configuration to the town’s south-west.

But the weather is against them. Snowfalls have softened the recognisable features of the land beneath, and despite the good visibility the Rhine is not easily seen. Nevertheless Darmstadt is reached at 00.42 and course is set for the ANTHROPOID pinpoint. As they fly east at about 10,000 feet the snowfalls cover the landscape, making accurate navigation using ground features impossible: “the heavy snow . . . blotted out all roads, railways, rivers, and small towns” — the major types of ground-feature used to identify a pinpoint. It is bitterly cold at that height: oxygen has to be used to help keep the crew warm and alert. Twice they encounter enemy aircraft, which nevertheless leave them alone. Low cloud increases to 10/10ths, and they lose height gradually from their cruise height of about 10,000 ft. At 02.12 they see flak ahead, and identify its source as Pilsen. According to Freddie Clark, the target area is near Borek aerodrome, south-east of Pilsen and some 80 km south of Prague. (This I have yet to check against the SOE file, currently on loan to Paris.) Instead the agents are dropped blind near the village of Nehvizdhy, some 22 kilometres east of Prague. Hockey may have flown over the capital, Prague, without realising it.

Hockey then sets course for the SILVER A and SILVER B target. From Hockey’s report it is clear that he is unaware of his location. As he is way off course, it follows that the second and third sets of drops will also be off-target. Moreover, in his report Hockey hints that his orders, at least regarding SILVER A & B, are to drop these teams regardless of whether he can find the precise target: ‘Both the two latter operations were completed under difficult conditions owing to their urgent nature and according to instructions received before take-off.’

Having completed all three operations, Hockey sets course for Darmstadt, but does not see it on the return leg. His account implies that they realise their true position only when fired-at over Brussels. They fly over Lille, and cross the French coast near Fécamp at 07.20. As they cross the Channel the cockpit’s overhead hatch flies open, and Dick Wilkin has to hang on to it until they land, to stop it coming adrift and fouling the tailplane controls; Hockey reduces speed to 140 mph. They cross the English coast near Selsey Bill at 08.07, and land back at Tangmere twelve minutes later.

This operation shows that the Special Duties crews, when faced with similar conditions to those faced by the main force bomber crews, fared little better. Their ability to find a pinpoint deep in enemy-occupied Europe depended on pinpoint-to-pinpoint navigation at relatively low level. At 10,000 feet the ground beneath, if it is visible at all, appears very different from the detailed view available at 2,000-4,000 feet; under deep snow, even a city is rendered almost invisible at that height in poor visibility. By the time Hockey arrived over Czechoslovakia there was heavy cloud; had he not encountered flak he and his crew might have had little idea of where they were.
