The Battle of the Persian Border was the second encounter between the forces of Media and Persia.
 Though not a decisive victory for Persia, it signaled the diminishing power of Media in Southwest Asia.
 It was the first battle Cambyses I had fought in, and the first which he had fought with his son, Cyrus the Great.
 The first major battle, which lasted two days, was an attempt to bring freedom to Persia.
 It also prompted the Persians to retire south, and fight a third battle.
 It was narrated by Nicolaus of Damascus, and among others who also mentioned the Battle of Hyrba, but Herodotus does not mention this battle.
 Most historians on the battle consider Herodotus to be mentioning only the first and last battles in the war, which is partly based on the description of his two battles.
 At the border this became the first major battle between the two powers.
 Cyrus managed to escape the enemy without retreating, thus ending the battle and prolonging the struggle without a complete victory for Astyages, the king of the Medes.
 The next battle became the last stand for the Persians; as their very existence relied on the outcome of the war, which had to be won.
The Schwarze Kapelle (German for "Black Orchestra") was a term used by the Gestapo to refer to a group of conspirators within the German military who plotted to overthrow Adolf Hitler.
 It included many senior officers within the Wehrmacht.
 Unlike the "Rote Kapelle" (Red Orchestra), the name given by the Gestapo to the Soviet spy network within the Third Reich, the members of the "Black Orchestra" were of aristocratic background, felt contempt for the ideological fervor of the Nazi Party and were politically closer to the Western Allies.
Stopped at Stalingrad: The Luftwaffe and Hitler's Defeat in the East, 1942-1943 is a book that analyzed the role of Hitler's use and control of the Luftwaffe in the Battle of Stalingrad between Nazi Germany and the Soviet Union during World War II.
 Written by New Zealand-born British scholar Joel S. A. Hayward, it discusses at length the various reasons for Hitler's invasion, the consequences, the major battles of the Eastern Front and the role of the Luftwaffe in these areas, along with the hierarchy of the Luftwaffe itself.
 The book deals with how Hitler's control of the Luftwaffe during this battle ultimately led to the German loss at the Battle of Stalingrad, the turning point against the Germans in World War II.
The Battle of Stalingrad (23 August 1942 – 2 February 1943) was a major battle of World War II in which Nazi Germany and its allies fought the Soviet Union for control of the city of Stalingrad (now Volgograd) in Southern Russia.

Stalingrad, a Soviet city and industrial centre on the river Volga, was bombed heavily by the Luftwaffe during the Battle of Stalingrad in World War II.
 German land forces comprising the 6th Army had advanced to the suburbs of Stalingrad by August 1942.
 The city was extensively bombed as a precursor to the 6th Army's first major ground offensive against the city on by 16th Panzer Division on 23 August, breaking out from its bridgehead on the River Don north-west of the city.

Manfred Roeder (August 20, 1900 – October 18, 1971) was a military judge in Nazi Germany.
 Serving on the highest wartime court, he led the investigation and examinations and later the prosecution of the German Resistance group, the Red Orchestra.
 He shared responsibility for the dozens of death sentences handed down by the Reich court martial to Red Orchestra members.
 After Germany's defeat in World War II, there were attempts by survivors, family and the U.S. Army to investigate the prosecutions of Red Orchestra members and others, but Roeder was never convicted of any malfeasance or crime because the Allies thought it more expedient to use his 'expertise' to hunt down the Red Orchestra members a second time than to mete out justice for victims of the Nazis; this time to aid the Western Allies with information about the Russians in the nascent cold war.
The 10th Rifle Division 'Stalingrad' of the Order of Lenin of the Internal Troops of the NKVD of the USSR (Russian: 10-я стрелковая Сталинградская ордена Ленина дивизия внутренних войск НКВД СССР ) was a Soviet rifle division formed on 1 February 1942 prior to the Battle of Stalingrad during the Great Patriotic War and participated in heavy front-line actions which would significantly reduce its strength by the battle's end.
 It was under the jurisdiction of the Internal Troops of the NKVD but took strategic orders from the 62nd Army command.
 Later it converted into a regular Red Army division and was renamed the 181st "Order of Lenin" "Stalingrad" Rifle Division.
KLK Calling PTZ – The Red Orchestra (alternate title: "KLK To PTX - The Red Band"; German: "KLK an PTX – Die Rote Kapelle") is a 1971 East German film about the history of the Red Orchestra espionage ring.
