Question: What war was Operation Lucid and Operation Sea Lion planned during?

Context paragraphs:
New Zealand sea lion: The New Zealand sea lion ("Phocarctos hookeri"), also known as Hooker's sea lion, and whakahao in Māori, is a species of sea lion that primarily breeds on New Zealand's subantarctic Auckland and Campbell islands and to some extent around the coast of New Zealand's South and Stewart islands.  The New Zealand sea lion numbers around 10,000 and is perhaps the world's rarest sea lion species.  They are the only species of the genus "Phocarctos".

Operation Lucid: Operation Lucid was a British plan to use fire ships to attack invasion barges that were gathering in ports on the northern coast of France in preparation for a German invasion of Britain in 1940.  The attack was initiated several times in September and October that year, but unreliable ships and unfavourable weather caused the plan to be aborted on each occasion.

Sea lion: Sea lions are sea mammals characterized by external ear flaps, long foreflippers, the ability to walk on all fours, and short, thick hair, big chest and belly.  Together with the fur seals, they comprise the family Otariidae, eared seals, which contains six extant and one extinct species (the Japanese sea lion) in five genera.  Their range extends from the subarctic to tropical waters of the global ocean in both the Northern and Southern Hemispheres, with the notable exception of the northern Atlantic Ocean.  They have an average lifespan of 20–30 years.  A male California sea lion weighs on average about 300 kg and is about 8 ft long, while the female sea lion weighs 100 kg and is 6 ft long.  The largest sea lion is Steller's sea lion, which can weigh 1000 kg and grow to a length of 10 ft .  Sea lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight (about 15 – ) at a single feeding.

Operation Sea Lion order of battle: The German plan for a land invasion of England in 1940 was code-named Operation Sea Lion ("Unternehmen Seelöwe" in German).  This is the Operation Sea Lion order of battle for the modified German plan produced in August, 1940.

Steller sea lion: The Steller sea lion ("Eumetopias jubatus") also known as the northern sea lion and Steller's sea lion, is a near threatened species of sea lions in the northern Pacific.  It is the sole member of the genus "Eumetopias" and the largest of the eared seals (Otariidae).  Among pinnipeds, it is inferior in size only to the walrus and the two elephant seals.  The species is named for the naturalist Georg Wilhelm Steller, who first described them in 1741.  The Steller sea lion has attracted considerable attention in recent decades due to significant, unexplained declines in their numbers over a large portion of their range in Alaska.

The Battle of Britain: The Battle of Britain was the fourth of Frank Capra's "Why We Fight" series of seven propaganda films, which made the case for fighting and winning the Second World War.  It was released in 1943 and concentrated on the German bombardment of the United Kingdom in anticipation of Operation Sea Lion, the planned Nazi invasion of Great Britain.

Operation Sea Lion: Operation Sea Lion, also written as Operation Sealion (German: "Unternehmen Seelöwe" ), was Nazi Germany's code name for the plan for an invasion of the United Kingdom during the Battle of Britain in the Second World War.  Following the Fall of France, Adolf Hitler, the German Führer and Supreme Commander of the Armed Forces, hoped the British government would seek a peace agreement and he reluctantly considered invasion only as a last resort if all other options failed.  As a precondition, he specified the achievement of both air and naval superiority over the English Channel and the proposed landing sites, but the German forces did not achieve this at any point during the war and both the German High Command and Hitler himself had serious doubts about the prospects for success.  A large number of barges were gathered together on the Channel coast, but, with air losses increasing, Hitler postponed Sea Lion indefinitely on 17 September 1940 and it was never put into action.

Operation Green (Ireland): Operation Green (German: "Unternehmen Grün" ) often also referred to as Case Green ("Fall Grün" ) or Plan Green ("Plan Grün" ), was a full-scale operations plan for a Nazi German invasion of Ireland in support of Operation Sea Lion ("Unternehmen Seelöwe" ), the invasion of the United Kingdom, during World War II.  Despite its detailed nature, Green is thought to have been designed only as a credible threat, a feint, not an actual operation.  Plan W, a planned occupation of all of the state by the British Armed Forces, was drafted by the British military in secret liaison with the Irish government to counteract any German invasion.

South American sea lion: The South American sea lion ("Otaria flavescens", formerly "Otaria byronia"), also called the southern sea lion and the Patagonian sea lion, is a sea lion found on the Ecuadorian, Peruvian, Chilean, Argentinean, Uruguayan, and Southern Brazilian coasts.  It is the only member of the genus "Otaria".  Its scientific name was subject to controversy, with some taxonomists referring to it as "Otaria flavescens" and others referring to it as "Otaria byronia".  The former eventually won out, although that may still be overturned.  Locally, it is known by several names, most commonly lobo marino (es)/lobo marinho (pt) (sea wolf) and león marino (es)/leão marinho (pt) (sea lion).

Operation Sea Lion (wargame): Operation Sea Lion was a major wargame conducted at Royal Military Academy Sandhurst in 1974.  Its aim was find out what might have happened had Nazi Germany launched Operation Sea Lion, their planned invasion of southeast England during World War II, in September 1940.  The wargame was organized by the "Daily Telegraph" and Dr Paddy Griffith from the Department of War Studies at Sandhurst.  The British umpires were Air Chief Marshal Christopher Foxley-Norris, Rear Admiral Teddy Gueritz and Major General Glyn Gilbert.  The German umpires were General Adolf Galland (air), Admiral Friedrich Ruge (naval) and General Heinrich Trettner (land).  After the game's conclusion, the umpires unanimously concluded that the invasion was a devastating defeat for the German invasion force.
