South German Offensive: The South German Offensive is the general name of one of the final offensives of World War II in Europe.  The offensive was led by the Seventh and Third armies of the United States along with the First Army of France.  Soviet troops linked up with American forces in Czechoslovakia notably in the Battle of Slivice.  The offensive was made by the US 6th Army Group to protect the US 12th Army Group's right flank and to prevent a German last stand in the Alps.  However German resistance was much more fierce than in the north, which slowed the 6th Army Group's progress.  However, by the end of April, many German divisions surrendered without a fight to the advancing American forces to avoid the inevitable destruction.  The VI Corps of the Seventh Army linked up with the US Fifth Army, which fought through Italy, in the Alps as the Third Army advanced into Austria and Czechoslovakia, where it linked up with Soviet forces advancing from the east.  Fighting continued a few days after the Surrender of Germany on 8 May, due to German forces fighting west to surrender to the Americans instead of the Soviets.

Romanian armies in the Battle of Stalingrad: Two Romanian armies, the Third and the Fourth, were involved in the Battle of Stalingrad, helping to protect the northern and southern flanks respectively of the German 6th Army as it tried to conquer the city of Stalingrad, defended by the Soviet Red Army in mid to late 1942.  Overpowered and poorly equipped, these forces were unable to stop the Soviet November offensive which punched through both flanks and left the 6th Army encircled in Stalingrad.  The Romanians suffered enormous losses, which effectively ended their offensive capability on the Eastern Front for the remainder of the war.

Primorsky Military District: The Primorsky (Maritime Provinces) Military District was formed on September 30, 1945 on the territory of Primorsky Krai (territory of the former Ussuri Oblast), from HQ 1st Far East Front.  Under its control also were the troops stationed on the territory of North Korea (25th Army) and the Kwantung Peninsula (39th Army).  The district headquarters was in the city of Voroshilov (Ussuriisk).  Troops stationed in Primorsky Krai were the 5th and 35th Armies.  Air support was provided by the 9th Air Army.  The 35th Army, the 17th Rifle Corps and the 105th, 187th, 190th, 231st, 235th, 335th, 345th, 363rd, 365th and 366th Rifle Divisions were disbanded.  The 5th Army's two tank divisions, the 2nd and 3rd, were the only Soviet tank divisions in the Far East.  The 25th Army's 39th and 88th Rifle Corps were disbanded in August 1946.  Also during the summer of 1946, 39th Army's 91st Guards, 252nd, 338th and 358th Rifle Divisions were converted into the 4th, 25th and 26th Guards Machine Gun Artillery Brigades.  In 1947, these became the 25th Guards Machine Gun Artillery Division.  39th Army's 113th Rifle Corps disbanded in January 1947.  25th Army pulled out of North Korea in 1948 and was stationed in southern Primorsky Krai on Sino-North Korean border and on the coast of the Peter the Great Gulf.  By 1948, the army only included the 10th Mechanized and 40th Rifle Divisions, as its other units had all disbanded before 1948.

Tatsinskaya Raid: The Tatsinskaya Raid was a Soviet armoured raid deep into the German rear conducted by 24th Tank Corps under the command of Major General Vasily Mikhaylovich Badanov in late December 1942, during the last phases of the Battle of Stalingrad (Operation Little Saturn).  It was designed to force the Germans to divert forces attempting to relieve the 6th Army trapped in Stalingrad.  The Soviet force captured its objective, the Luftwaffe's airfield at Tatsinskaya, destroying over 72 aircraft on the ground, but was left cut off and without supplies.  Despite the loss of most of the tank corps during the ensuing breakout, the raid was a great operational victory.

Constantin Brătescu: Constantin Brătescu (March 8, 1892 - April 13, 1971) was a Romanian Major-General during World War II.  In 1941, he served first as Chief Propaganda Section General Staff (Romania's Propaganda Minister) and then as a Romanian liaison officer to the German Military Mission, meaning that he served as a German military officer during Operation Barbarossa and the Axis Invasion of the Soviet Union.  Starting in 1942 Brătescu was a Romanian General Officer (at the rank of Major-General) and commanded the 1st Cavalry Division throughout the campaign against the Soviets, fighting in such engagements as Operation Barbarossa, Operation Blue, and the Battle of Stalingrad.  Following the surrender of Friedrich Paulus' 6th Army at the Battle of Stalingrad, Brătescu became a prisoner of war and was held captive from 1943 to 1948.  Finally, in 1948, he was released after five years of imprisonment and subsequently retired from active service.  Bratescu ultimately died twenty-three years later, in 1971, at the age of seventy-nine.

66th Army (Soviet Union): The 66th Army was a field army of the Red Army.  It was established in August 1942 from the 8th Reserve Army.  The 66th Army fought to break through to the Volga to the north of Stalingrad during September and October 1942.  During Operation Uranus, the Soviet encirclement of German troops in Stalingrad, 66th Army troops linked up with those of the 62nd Army, forming the inner encirclement.  Until February the army fought to destroy the pocket and then was held in reserve.  In May 1943 it became the 5th Guards Army for its actions during the Battle of Stalingrad.

Bombing of Stalingrad: 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. `

62nd Army (Soviet Union): The 7th Reserve Army was formed 28 May 1942 as part of the Stavka Reserve (RVGK).  Within one month, this force had been redesignated the 62nd Army.  From mid August 1942 until late January 1943, the 62nd Army, under the command of General Vasily Chuikov, fought in the Battle of Stalingrad.  62nd Army conducted an epic defense of the city against repeated and desperate attacks by the German 6th Army.  The Army, along with the 64th Army, was operating under the Soviet Stalingrad Front.  After the German assault at Stalingrad had come to utter disaster, the 62nd Army was uniquely awarded the Order of Lenin, and granted Guards status as the 8th Guards Army.

Siege of Mogilev: The Siege of Mogilev was a three-week encirclement of Mogilev undertaken by German troops, part of the Battle of Smolensk.  After the beginning of Operation Barbarossa, the German invasion of the Soviet Union, German troops broke through Soviet lines.  Mogilev was heavily fortified and bypassed by German tank forces.  German infantry steadily reduced the pocket, and by late July, the defending Soviet troops had run out of ammunition and other necessary supplies.  As a result, Soviet commander Fyodor Bakunin went against orders and ordered a breakout.  A small number of Soviet troops were able to reach Soviet lines, and 35,000 were reported captured by German troops.  The defense of Mogilev tied down four German infantry divisions, delaying their attack on Gomel for a week.

Friedrich Paulus: Soviet troops took Paulus by surprise and captured him in Stalingrad on 31 January 1943, the same day on which he was informed of his promotion to field marshal ("Generalfeldmarschall") by Adolf Hitler.
