[Q]: Question: How long had Shumilov been in the military when the Soviet invaded Poland? Passage:Colonel (promoted to Major General 4 June 1940) Mikhail Shumilov took command in April 1938. In September 1939, the corps fought in the Soviet invasion of Poland as part of the 10th Army. It included the 6th, 33rd, and the 121st Rifle Divisions at the beginning of the invasion on 17 September. By 2 October, these divisions had transferred to other units, and it included the 29th, 64th, and 145th Rifle Divisions instead. The corps headquarters relocated to Grodno in November and became part of the 11th Army. Between June and July 1940 it was briefly headquartered at Kovno before moving to Šiauliai in August, part of the Baltic Special Military District. The 11th transferred to the 8th Army in October, and included the 11th and 125th Rifle Divisions by the outbreak of the war. It defended a 40-kilometer sector on the left flank of the 8th Army, with its headquarters in the forests northwest of Skaudvilė.

[Q]: Question: Was Erich von Drygalski married when he led the German Antarctic expedition? Passage:While Borchgrevink, steering towards the Southern Cross, was on target for Antarctica, a German, Swedish and British expedition was prepared for the Southern Ocean. Germany built the expedition ship Gauss for 1.5 million marks at the Howaldtswerke in Kiel. On the model of the Fram, the Gauss, which weighed 1,442 tonnes (1,419 long tons) and was long, had a round hulk in order to withstand the ice pressure. The Gauss had three masts and one auxiliary engine of 275 horsepower (205 kW). With a 60-strong crew, it could operate for almost three years without any help. From 1901 until 1903, Erich von Drygalski led the German Antarctic expedition and carried out extensive studies mainly in the southern part of the Indian Ocean. The Swedish expedition under the command of Otto Nordenskjöld used the old Antarctic weighing only 353 tonnes, which had already been used by Borchgrevink in 1895. The expedition intending to overwinter at the Antarctic Peninsula was ill-starred from the beginning. In 1902, the Antarctic sank. Fortunately, the Argentine gunboat Uruguay rescued all crewmembers. Also Great Britain prompted Dundee Shipbuilders to build a ship for Robert Falcon Scott's expedition. The Discovery weighed 1620 tonnes, was long and had an auxiliary motor of 450 horsepower. Nevertheless, during the research the ship froze in. Only the relief ship Morning, sent by the British Admiralty, was able to free the Discovery and with Terra Nova escorted the Discovery back home. The reunion with the Antarctic ice was undertaken by a Scottish expedition led by the naturalist William Speirs Bruce. Bruce had worked with the whale catchers Balaena and Active in the Southern Ocean in 1892 to 1893. He hoped that he could acquire the field-tested Balaena but found the ship too expensive, buying instead the Norwegian whale catcher Hekla for £2,620, a ship that had sailed under the Danish flag along Greenland's coast in 1891 and 1892. For another £8,000 he had the ship repaired and provided it with a new engine. Under the new name Scotia, this ship completed its way into the Southern Ocean and was very successful thanks to dredging and trawl catches at great depth in the Weddell Sea and off the coast.
