Question 1 of 10
1. German armed forces invaded Norway on 9th April 1940. Within 24 hours the German army had taken control of every major city and the peaceful nation of Norway stood little chance against the German war machine.
However, the Norwegians did succeed in sinking which German heavy cruiser?
Hint


Question 2 of 10
2. After the successful invasion of Norway, Germany had access to the long Norwegian coastline which was ideal for launching attacks against the Allied Atlantic convoys. The Germans also now had access to a plant capable of producing significant stocks of heavy water, required to construct an atomic weapon. The plant was situated in the region of Telemark. What was the plant known as? Hint


Question 3 of 10
3. Although existing stocks of heavy water had been smuggled out of the plant shortly before the Germans invaded, the British government still had cause for extreme concern. Intelligence reports suggested that the Germans were continuing the production of heavy water and intended to increase it significantly.
This situation led to the realisation that action had to be taken to prevent the Germans obtaining any advantage over the Allies in the development of atomic weapons.
In a meeting held in 1942 attended by atomic scientists who were attached to the British Royal Marines, the Royal Norwegian Army and the SOE, which action was actually considered but NOT carried out?
Hint


Question 4 of 10
4. When selecting men for the attack on the plant, the Special Operations Executive decided to avoid recruiting from the many Norwegians who had managed to arrive in the United Kingdom after escaping from occupied Norway.
It was felt that the risk of reprisals by the Germans was too high for their families in the event of their capture.


Question 5 of 10
5. In March 1942, a young Norwegian arrived in Aberdeen, Scotland by steamer. He and his compatriots had seized the SS Galtesund and made their escape from occupied Norway. This was an excellent turn of events for the SOE. This young man was an engineer at the plant and had contacts and local knowledge of the area, therefore was a valuable asset to the SOE. What was his family name? Hint


Question 6 of 10
6. Several operations were planned and executed with the ultimate aim of halting heavy water production at the plant. Which operation involved towing gliders by heavy bombers to Norway but resulted in disaster?
Hint


Question 7 of 10
7. The group of brave Norweigian saboteurs who made up Operation Gunnerside, an operation designed to destroy the plants heavy water production capability, left an item behind during the raid. This was a deliberate act in an attempt to convince the Germans that foreign powers were behind the raid, not the local resistance. The hope was to lessen the likelihood of reprisals against the local population by the Germans.
What was the item?
Hint


Question 8 of 10
8. The events surrounding Operation Gunnerside were made into the 1965 film "The Heroes of Telemark". Norwegian veterans of the raid commented that the film did not accurately portray the events that actually occured. The film featured a famous American actor. What was his name? Hint


Question 9 of 10
9. In 1944, due to the campaign of air raids carried out by the USAAF against the plant, the Germans made the decision to move their stock of heavy water to Germany. However, the heavy water never completed its journey. What happened?
Hint


Question 10 of 10
10. Most of the barrels of heavy water have remained under water for over 60 years, but which museum now has barrel number 26 on display? Hint

Quiz Answer Key and Fun Facts
1. German armed forces invaded Norway on 9th April 1940. Within 24 hours the German army had taken control of every major city and the peaceful nation of Norway stood little chance against the German war machine. However, the Norwegians did succeed in sinking which German heavy cruiser?

Answer: Blücher

The Blücher was sunk with the loss of almost 1,000 lives. She was attacked by Norwegian coastal defences at Oslo's Oscarsborg port, which included the use of guns installed in 1893. The attack on the Blücher led to a delay in the German landings at Oslo and allowed time for the Norwegian royal family and government to escape to England.

The Prinz Eugen was a sister ship of the Blücher, famous for fighting along side the Bismarck agaisnt HMS Hood.

The Hindenburg was completed by Germany in 1917 and was scuttled in 1919.
2. After the successful invasion of Norway, Germany had access to the long Norwegian coastline which was ideal for launching attacks against the Allied Atlantic convoys. The Germans also now had access to a plant capable of producing significant stocks of heavy water, required to construct an atomic weapon. The plant was situated in the region of Telemark. What was the plant known as?

Answer: The Norsk Hydro Plant

The Norsk Hydro Plant is situated in a valley, halfway up a cliff in Vemork. It is about 150 miles from Oslo and the nearest town is Rjukan. The plant remains today and has been converted into a museum.

The Rjukan Hydro Generating Station, The Vemork Hydro Plant and Oslo Telemark Generator 3 are figments of my imagination.
3. Although existing stocks of heavy water had been smuggled out of the plant shortly before the Germans invaded, the British government still had cause for extreme concern. Intelligence reports suggested that the Germans were continuing the production of heavy water and intended to increase it significantly. This situation led to the realisation that action had to be taken to prevent the Germans obtaining any advantage over the Allies in the development of atomic weapons. In a meeting held in 1942 attended by atomic scientists who were attached to the British Royal Marines, the Royal Norwegian Army and the SOE, which action was actually considered but NOT carried out?

Answer: Send in a suicide squad to destroy the plant, with no chance of escape

The actual options considered were:
-Send in a suicide squad to destroy the plant, with no chance of escape;
-Use men employed at Vemork to blow up the stock of heavy water;
-Deploy agents to infiltrate the plant;
-Send in a SOE sabotage unit;
-RAF bombing;
-A Combined Operations attack using seaplanes to arrive and escape

The SOE (Special Operations Executive) was initiated by the British Prime Minister Winston Churchill and Labour MP Hugh Dalton, in July 1940. Both recognised a need for "irregular" warfare in addition to traditional armed forces. "Irregular warfare" included activities such as espionage and sabotage behind enemy lines.
4. When selecting men for the attack on the plant, the Special Operations Executive decided to avoid recruiting from the many Norwegians who had managed to arrive in the United Kingdom after escaping from occupied Norway. It was felt that the risk of reprisals by the Germans was too high for their families in the event of their capture.

Answer: False

The SOE chose to recruit from the many brave Norwegians who had escaped from their occupied land to the United Kingdom, most leaving family behind in Norway.
The British could see the obvious advantage of choosing men who had local knowledge of the country and language, not to mention a desire to hurt those who had invaded their homeland.
There was no shortage of volunteers; those who were chosen were subjected to a strenuous training program in preparation for their dangerous missions.
Capture by the Germans would have resulted in torture and the possible execution of themselves, their families and friends.
5. In March 1942, a young Norwegian arrived in Aberdeen, Scotland by steamer. He and his compatriots had seized the SS Galtesund and made their escape from occupied Norway. This was an excellent turn of events for the SOE. This young man was an engineer at the plant and had contacts and local knowledge of the area, therefore was a valuable asset to the SOE. What was his family name?

Answer: Skinnarland

The SOE recognised the importance of Einar Skinnarland as he worked at the Vemork plant and knew others who were dedicated to the resistance cause.
Skinnarland was trained by the SOE and returned to Telemark by parachute to gather intelligence on German activities at the plant.

Stensones and Peterson are random names.

Tito was the surname of the famous Yugoslavian WWII resistance leader.

Skinnarland was just one of many brave Norwegians who risked their lives against the occupiers of their country.
6. Several operations were planned and executed with the ultimate aim of halting heavy water production at the plant. Which operation involved towing gliders by heavy bombers to Norway but resulted in disaster?

Answer: Operation Freshman

Operation Freshman began on 19 November 1942. Two gliders containing members of the Royal Engineers were towed to Norway where bad weather led to crash landings causing a number of deaths. The survivors were captured by German forces - and all were executed.
Grouse, Swallow and Gunnerside were also operations launched against the plant.
7. The group of brave Norweigian saboteurs who made up Operation Gunnerside, an operation designed to destroy the plants heavy water production capability, left an item behind during the raid. This was a deliberate act in an attempt to convince the Germans that foreign powers were behind the raid, not the local resistance. The hope was to lessen the likelihood of reprisals against the local population by the Germans. What was the item?

Answer: A British machine gun

Concern for the risk of German reprisals against the local population was high. In order to reduce German suspicion that local resistance fighters were involved in the raid, a British machine gun was left at the plant. The saboteurs set explosives which detonated successfully, releasing the stock of heavy water. Unfortunately, the plant was restored to working order within two months.
8. The events surrounding Operation Gunnerside were made into the 1965 film "The Heroes of Telemark". Norwegian veterans of the raid commented that the film did not accurately portray the events that actually occured. The film featured a famous American actor. What was his name?

Answer: Kirk Douglas

Kirk Douglas is an iconic American actor and has a star on the Hollywood Walk of Fame for his contribution towards the motion picture industry. He has played in too many movies to mention here.

Gregory Peck and Lee Marvin are also famous Hollywood actors in thier own right.
The British TV presenter and author Ray Mears made a television documentary entitled "The Real Heroes of Telemark" in 2003.

A mixture of dramatisation and fact, it gave viewers a realistic insight to the events that took place in the fight for heavy water. The associated book from the programme, also called "The Real Heroes of Telemark" by Ray Mears is recommended if you are interested in the subject.
9. In 1944, due to the campaign of air raids carried out by the USAAF against the plant, the Germans made the decision to move their stock of heavy water to Germany. However, the heavy water never completed its journey. What happened?

Answer: The ferry carrying the drums of heavy water was sabotaged with explosives and sank complete with its cargo

The German plan to transport the heavy water was foiled by Knut Haukelid, a Norwegian commando. A ferry, the D/F Hydro was to take the cargo across Lake Tinnsjø, but Haukelid managed to get on board and plant explosives which detonated, resulting in the sinking of the ferry and its cargo. Several Norwegian civilians lost their lives in the sinking of the ferry.

The Junkers JU52 was a German transport aircraft known for its unusual corrugated skin. Its slow speed meant it was extremely vulnerable to attack by fighter aircraft.

HMS Campbeltown, formally known as USS Buchanan was transferred from the US Navy to the Royal Navy in 1940. She is probably most known for her involvement in Operation Chariot, where she rammed the dock gates at Saint-Nazaire in an attempt to destroy the facilities sufficiently to prevent the German battleship Tirpitz from entering dry dock.

The Sturgeon was a British submarine launched in 1932. She sank several ships, mainly merchant and in 1943 she was transferred to the Netherlands Navy and renamed Zeehond.
10. Most of the barrels of heavy water have remained under water for over 60 years, but which museum now has barrel number 26 on display?

Answer: The National World War II Museum, New Orleans, USA

Thor Olav Sperre, Jonny Skogstad and Fredrik Søreide were responsible for the recovery of barrel number 26 from the wreck the D/F Hydro in 2004. The barrel is now at the National World War II Museum in New Orleans.
