Moorook West Wood Camp: Moorook West (Wood Camp) was a short lived World War II prisoner of war camp in the Australian state of South Australia, located in Loveday near the River Murray, in the state's Riverland.  It was officially part of the Loveday POW Camp complex, and housed Japanese prisoners of war.  They were employed as wood cutters for the Allied war effort.  It was similar to wood camps throughout South Australia at the time, including two others attached to the Loveday POW camps - Woolenook (Wood Camp) and Katarapko (Wood Camp).  The camp was officially closed on 21 February 1943.

Death in Captivity: Death in Captivity is a mystery novel by the British crime writer Michael Gilbert, first published in the United Kingdom in 1952 by Hodder and Stoughton and in the United States by Harper & Brothers as "The Danger Within".  It was Gilbert's sixth novel and, unlike his previous ones, does not feature Chief Inspector Hazlerigg in any way.  Nor is it set in Gilbert's usual locales of London, the English countryside, or France.  Instead, while it has many of the elements of the classic detective story, it is also a gripping novel of mounting suspense that takes place in a 1943 prisoner of war camp for British officers in northern Italy—it was the first of Gilbert's numerous later works that would feature suspense and danger as much or more as elements of detection.  Gilbert himself had been a British officer during the war, was captured, and interned in an Italian camp.  He escaped and spent several months making his way through the Italian countryside trying to reach the British lines.  Much of this book apparently reflects his own experiences.  It was the basis of a 1959 British film, Danger Within (Breakout in the United States), that closely followed the events in the book.  H.R.F. Keating, who wrote Gilbert's obituary for The Guardian, said that "Gilbert's time as a PoW prompted Death In Captivity (1952), surely the only whodunnit set in a prisoner-of-war camp."

Joseph H. Tucker: Joseph H. Tucker (1819  – October 22, 1894) was a banker, businessman and Illinois militia colonel during the first two years of the American Civil War (Civil War).  He was given initial responsibility for building Camp Douglas at Chicago, Illinois, and was the first commander of the camp.  Originally a training camp for Union Army recruits, in 1862 and 1863 Camp Douglas was converted into a prison camp for Confederate States Army prisoners captured by the Union Army.  Tucker was commander of the camp from the start of its construction in October 1861 until September 28, 1862, except between February 26, 1862, and June 19, 1862.  During this time, the camp was used as a training facility and had its initial use as a prisoner of war camp.  Tucker was never mustered into the Union Army, remaining a colonel in the Illinois militia during the term of his service in the Civil War.

Colditz Castle: 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.

Camp Michaux: Camp Michaux was a secret World War II camp for interrogating prisoners of war.  The camp northwest of the Pine Grove Iron Works was previously used as a CCC camp that provided labor for state-owned lands (e.g., Pine Grove Furnace State Park) and was used as a summer camp.  The POW camp commander was Captain Lawrence C. Thomas, who also commanded the World War II Prisoner of War Camp, Gettysburg Battlefield, Pennsylvania.

Katarapko Wood Camp: Katarapko Wood Camp was a World War II prisoner of war camp, located on Katarapko Island, on the River Murray near Loxton, in South Australia's Riverland.  It was officially part of the Loveday POW Camp complex, and housed Italian prisoners of war, who were employed as wood cutters for the Allied war effort.

Hajime Toyoshima: 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.
