Example Input: Passage: Seed spent the 1914–15 season playing in Sunderland reserves, he scored plenty of goals as the team lifted the Durham Senior Cup. Official League football was suspended at the end of that season because of the outbreak of World War I. At the end of the season, the 20-year-old Seed joined the Army Cyclist Corps. In the summer of 1916, he was drafted to France with the 8th battalion of the West Yorkshire Regiment. Seed suffered with depression after his arrival and in July 1917, he was gassed when a German aeroplane dropped mustard gas bombs on a house in Nieuwpoort, Belgium, in which he was sleeping. He returned to England to convalesce and returned to France in August 1918, until being evacuated after being gassed in Valenciennes, France two months later. With the cessation of hostilities, Seed played a Victory League match for Sunderland against Durham City in 1918, however his lungs were weak and he had a poor game. On the strength of that performance the Sunderland directors decided that Seed's wartime experience had finished him as a footballer and gave him a free transfer. Seed never played an official first team game for Sunderland. Seed was discharged from the army in March 1919.

Example Input: Passage: At the time, the Thirty Years' War was raging across Europe. Gabriel Bethlen, prince of Transylvania saw an opportunity to unite the two Hungarian principalities, Transylvania and Royal Hungary, and sacked Vienna in November 1619. He also asked Sultan Osman II for aid, but this was unsuccessful. The Commonwealth was relatively uninvolved in this war but the Polish king, Zygmunt III Waza, sent an elite and ruthless mercenary unit, the Lisowczycy, to aid his Habsburg allies. They defeated the Hungarian lord George Rákóczi at the Battle of Humenné in 1619, and thus, cut the supply lines of Transylvanian forces. Then Gaspar Graziani, ruler of Moldavia, switched sides and joined Poland.
