Question:  The Siege of Tyre was an assault by the founder of what?

<P0-S0> The Siege of Sevastopol is a painted panorama by the Russian artist Franz Roubaud. <P0-S1>  It shows the Allied assault on the Malakhov Battery on 6 June 1855 during the Siege of Sevastopol during the Crimean War, in which 173,000 British and French troops were repulsed by 75,000 Russians. <P0-S2>  It features portraits of Pavel Nakhimov, the Russian nurse Dasha and Nikolay Pirogov. <P0-S3>  He painted it between 1902 and 1904. <P0-S4>  It was unveiled in a specially designed building in 1905, the fiftieth anniversary of the siege. <P0-S5>  It was damaged during the German siege of Sevastopol in 1942 and restored in the 1950s. <SEP> <P1-S0> The Siege of Tyre took place from November 12, 1187 to January 1, 1188. <P1-S1>  An army commanded by Saladin made an amphibious assault on the city, defended by Conrad of Montferrat. <P1-S2>  After two months of continuous struggle, Saladin dismissed his army and retreated to Acre. <SEP> <P2-S0> The Siege of Buda (Hungarian: "Buda ostroma" ) was the siege of the Buda castle, part of the twin capital cities of the Kingdom of Hungary by the Hungarian revolutionary army led by General Artúr Görgei, during the Hungarian War of Independence. <P2-S1>  It was part of the Spring Campaign, fought between 4 and 21 May 1849 and ended with the Hungarian capture of the castle by assault on 21 May. <P2-S2>  Actually it was the only fortress in the 1848-1849 Hungarian Freedom War, which was taken by the assault of the besieging troops of any of the fighting parts, the others being taken only after agreements between the besiegers and the besieged, with the capitulation of the latters, the capture of Buda on 21 May 1849 by assault being the only exception from this. <P2-S3>  The siege of Buda was also the shortest siege in the Hungarian Freedom War of 1848-1849 (18 days). <P2-S4>  The senseless bombardment of Pest by Major General Heinrich Hentzi, the Austrian commander of the city of Pest destroyed the classicist buildings from the shores of the Danube, but the other parts of the capitals also suffered heavy damages because of the artillery duels of the two parts. <P2-S5>  With the capture of the Buda Castle ended the complete liberation of the Hungarian capital cities (Buda and Pest), and thanks to this the second Hungarian revolutionary Government led by Bertalan Szemere together with Lajos Kossuth, the Governor-President of Hungary returned from Debrecen the interim capital of the Hungarian revolution, in the real capital of Hungary. <P2-S6>  At 21 May 1849, the same day with the capture of Buda, the two emperors: Franz Joseph I of Austria and tsar Nicholas I of Russia signed the final treaty which decided the involvement of 200 000 Russian soldiers (and a 80 000 strong reserve force, in the case that they were needed) in Hungary, in order to help the Habsburg Empire to crush the Hungarian revolution. <SEP> <P3-S0> An-Nasir Salah ad-Din Yusuf ibn Ayyub (Arabic: صلاح الدين يوسف بن أيوب‎ ‎ / ALA-LC: "Ṣalāḥ ad-Dīn Yūsuf ibn Ayyūb"; Kurdish: سەلاحەدینی ئەییووبی‎ / ALA-LC: "Selahedînê Eyûbî"), known as Salah ad-Din or Saladin ( ; 11374 March 1193), was the first sultan of Egypt and Syria and the founder of the Ayyubid dynasty. <P3-S1>  A Sunni Muslim of Kurdish ethnicity, Saladin led the Muslim military campaign against the Crusader states in the Levant. <P3-S2>  At the height of his power, his sultanate included Egypt, Syria, Upper Mesopotamia, the Hejaz, Yemen and other parts of North Africa.
