Context paragraphs:
Deutscher Morgen: Deutscher Morgen (also known as Aurora Alemã in Portuguese, meaning ""German morning"") was a German language Brazilian newspaper published between 16 March 1932 and December 1941.  Self-proclaimed the "official paper of the Nazi Party in Brazil", it was the largest Nazi newspaper of that country.  Installed in the neighborhood of Mooca, São Paulo during its early years and led by Hans Henning von Cossel, the "Deutscher Morgen" reported almost exclusively facts related to the Third Reich, disseminating statements made by Adolf Hitler and other exponents of the Nazi government.

Henning von Tresckow: Hermann Henning Karl Robert von Tresckow (10 January 1901 – 21 July 1944) was an officer in the German Army who helped organize German resistance against Adolf Hitler.  He attempted to assassinate Hitler on 13 March 1943 and drafted the Valkyrie plan for a coup against the German government.  He was described by the Gestapo as the "prime mover" and the "evil spirit" behind the plot of 20 July 1944 to assassinate Hitler.  He committed suicide at Królowy Most on the Eastern Front upon the plot's failure.

Joachim von Heydebreck: Joachim von Heydebreck (October 6, 1861 – November 12, 1914) was a German military officer who was born in Schwedt and grew up in Zützen.  He was the son of Prussian Lieutenant General Henning von Heydebreck (1828–1904) and his wife Anna von Colmar (1837–1879).

Operation Spark (1940): Operation Spark (sometimes translated as "Operation Flash") was the code name for the planned assassination of Nazi dictator Adolf Hitler by the anti-Nazi conspiracy of German army officers and political conservatives, known as the "Schwarze Kapelle" ("black band") during World War II.  The name was coined by Major General Henning von Tresckow in 1941.  He believed that because of Hitler's many successes up to that time, his personal charisma, and the oath of personal loyalty to him sworn by all German army officers, it would be impossible to overthrow Hitler and the Nazis while Hitler lived.  But Hitler's death would be a "spark" - a signal that it was time to launch an internal coup d'état to overthrow the Nazi regime and end the war.

Hans-Ulrich von Oertzen: Born in Berlin to an aristocratic family, Oertzen followed his father into the army and trained as a general staff officer.  During the Second World War he was promoted to Major and by 1943 was serving in Army Group Centre under Generalmajor Henning von Tresckow, who was one of the leading members of the resistance.  He then helped Claus von Stauffenberg to develop Operation Valkyrie.  On 26 March 1944, he married Ingrid von Oertzen Langenn, and a selection of 240 letters he wrote to her from 1942 to 1944 were recently published in book form in Germany.

Joachim von Tresckow: Joachim von Tresckow (20 June 1894 – 3 November 1958) was a German general during World War II.  He was a recipient of the Knight's Cross of the Iron Cross of Nazi Germany.

Operation Spark (1973): Operation Spark was a deception operation led by Syria and Egypt, aimed towards deceiving Israel of its intention to invade the Golan Heights and the Sinai Peninsula respectively, in 1973.  The operation succeeded in that Israeli intelligence was not, as a whole, able to inform a nationwide alert that war was imminent and that mobilisation should proceed apace; the established 48-hour warning had proved advantageous to Israel in previous wars, most notably the Six-Day War.

Claus von Stauffenberg: Claus Philipp Maria Schenk Graf von Stauffenberg (15 November 1907 – 21 July 1944) was a German army officer and member of the German nobility who was one of the leading members of the failed 20 July plot of 1944 to assassinate Adolf Hitler and remove the Nazi Party from power.  Along with Henning von Tresckow and Hans Oster, he was one of the central figures of the German Resistance movement within the "Wehrmacht".  For his involvement in the movement, he was executed by firing squad shortly after the failed attempt known as Operation "Valkyrie".

Operation Iskra: Operation Iskra (Russian: операция «Искра» , "operatsiya Iskra"; English: Operation Spark ) was a Soviet military operation during World War II, designed to break the German Wehrmacht's Siege of Leningrad.  Planning for the operation began shortly after the failure of the Sinyavino Offensive.  The German defeat in the Battle of Stalingrad in late 1942 had weakened the German front.  By January 1943, Soviet forces were planning or conducting offensive operations across the entire German-Soviet front, especially in southern Russia, Iskra being the northern part of the wider Soviet 1942–1943 winter counter offensive.

Joachim Christian von Tresckow: Joachim Friedrich Christian von Tresckow ( 28 September 1698 in Niegripp bei Magdeburg– 20 April 1762 in Neisse) was a Prussian Lieutenant General, Proprietor of the Prussian Infantry Regiment Nr.  32.  He was a Knight of the Black Eagle Order and a recipient of the Order Pour le Mérite.  He served Frederick the Great in the War of Austrian Succession and the Seven Years' War.
