Sergeant Hajime Toyoshima (豊嶋一 , Toyoshima Hajime ) (died August 5, 1944) was a Japanese airman in World War II.
 His A6M Zero was the first of that type (after those recovered after the Attack on Pearl Harbor) to be recovered relatively intact on Allied territory when he crash landed on Melville Island, Northern Territory, Australia.
 Toyoshima was the first Japanese Prisoner of War to be captured in Australia.
 While a Prisoner of War, Toyoshima was one of the instigators of the Breakout from the Prisoner of War Camp located in Cowra, New South Wales, Australia, sounding a bugle to signal the commencement of the escape and died during the escape attempt.
The Great Escape is an insider's account by Australian writer Paul Brickhill of the 1944 mass escape from the German prisoner of war camp Stalag Luft III for British and Commonwealth airmen.
 As a prisoner in the camp, he participated in the escape plan but was debarred from the actual escape 'along with three or four others on grounds of claustrophobia'.
 The introduction to the book is written by George Harsh, an American POW at Stalag Luft III.
 This book was made into the 1963 film "The Great Escape".
Stalag XX-A was a German World War II prisoner of war camp located in Thorn/Toruń, Poland.
 It was not a single camp and contained as many as 20,000 men at its peak.
 The main camp was located in a complex of fifteen forts that surrounded the whole of the city.
 The forts had been built at the end of the 19th century to defend the western border of Kingdom of Prussia.
Flight Lieutenant John William "Jack" Best MBE (6 August 1912 – 22 April 2000) was a British Royal Air Force pilot.
 He was a notable prisoner of war, who was held captive at Colditz Castle in eastern Germany during World War II.
 Best was noted for his several attempts to escape from Colditz and for his part in building the "Colditz Cock", a glider from which he hoped to escape by air.
Lieutenant Albert Michael Sinclair, DSO (26 February 1918 – 25 September 1944), known as the Red Fox, was a British prisoner at Colditz Castle (POW camp Oflag IV-C) during World War II.
 He was involved in a number of escape attempts and was recognised within the camp for his determination to escape.
 Sinclair was the only person to be killed while attempting to escape Colditz.
Castle Colditz (or "Schloss Colditz" in German) is a Renaissance castle in the town of Colditz near Leipzig, Dresden and Chemnitz in the state of Saxony in Germany.
 The castle is between the towns of Hartha and Grimma on a hill spur over the river Zwickauer Mulde, a tributary of the River Elbe.
 It had the first wildlife park in Germany when, during 1523, the castle park was converted into one of the largest menageries in Europe.
 The castle gained international fame as the site of Oflag IV-C, a prisoner-of-war camp during World War II for "incorrigible" Allied officers who had repeatedly escaped from other camps.
Stalag VI-C was a World War II German POW camp located 6 km west of the village Oberlangen in Emsland in north-western Germany.
 It was originally built with five others in the same marshland area as a prison camp ("Straflager") for Germans.
 From 1939 till 1945 the Oberlangen camp was a Prisoner of War camp.
Escape from Colditz is a strategy card and dice-based board game produced by Gibsons Games and first released in 1973.
 It was licensed to Parker Brothers in the US in the mid-1970s.
 The game was devised by successful escaper Pat Reid, based on the prisoner-of-war camp (Oflag IV-C) at Colditz Castle in Germany during World War II.
Patrick Robert Reid, MBE, MC (13 November 1910 – 22 May 1990) was a British Army officer and author of historical non-fiction.
 As a British prisoner of war during the Second World War, he was held captive at Colditz Castle when it was designated Oflag IV-C.
 Reid was one of the few to escape from Colditz, crossing the border into neutral Switzerland in late 1942.
 After the war Reid was a diplomat and administrator before eventually returning to his pre-war career in civil engineering.
 He also wrote about his experiences in two best-selling books, which became the basis of a film, TV series and even a board game.
Etienne Henri "Hans" Larive, MWO, DSC and bar, (23 September 1915 – 28 December 1984) was a Dutch naval officer during World War II.
 He escaped from the prisoner of war camp Oflag IV-C at Colditz Castle in 1941, and spent the rest of the war in England serving aboard Motor Torpedo Boats.
 He later wrote his memoir "Vannacht varen de Hollanders" (1950), which was republished translated into English as "The Man Who Came in From Colditz" (1975) – a pun on the best-selling novel "The Spy Who Came in from the Cold".
