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

Context paragraphs:
Siege of Tyre (1187): The Siege of Tyre took place from November 12, 1187 to January 1, 1188.  An army commanded by Saladin made an amphibious assault on the city, defended by Conrad of Montferrat.  After two months of continuous struggle, Saladin dismissed his army and retreated to Acre.

Siege of Buda (1849): 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.  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.  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.  The siege of Buda was also the shortest siege in the Hungarian Freedom War of 1848-1849 (18 days).  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.  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.  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.

Phoenicia under Hellenistic rule: The Persian Empire, including modern Lebanon, eventually fell to Alexander the Great, king of Macedonia.  He attacked Asia Minor, defeated the Persian troops in 333 BC, and advanced toward the Lebanese coast.  Initially the Phoenician cities made no attempt to resist, and they recognized his suzerainty.  However, when Alexander tried to offer a sacrifice to Melqart, Tyre's god, the city resisted.  Alexander besieged Tyre in retaliation in early 332 BC.  After seven months of resistance, the city fell, and its people were sold into slavery (See Siege of Tyre (332 BC)).  Despite his early death in 323 BC, Alexander's conquest of the eastern Mediterranean Basin left a Greek imprint on the area.  The Phoenicians, being a cosmopolitan people amenable to outside influences, adopted aspects of Greek civilization with ease.

Roman siege engines: Roman siege engines were, for the most part, adapted from Hellenistic siege technology.  Relatively small efforts were made to develop the technology; however, the Romans brought an unrelentingly aggressive style to siege warfare that brought them repeated success.  Up to the 1st century BC the Romans utilized siege weapons only as required and relied for the most part on ladders, towers and rams to assault a fortified town.  Ballistae were also employed, but held no permanent place within a legion's roster, until later in the Republic, and were used sparingly.

Siege of Sevastopol (panorama): The Siege of Sevastopol is a painted panorama by the Russian artist Franz Roubaud.  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.  It features portraits of Pavel Nakhimov, the Russian nurse Dasha and Nikolay Pirogov.  He painted it between 1902 and 1904.  It was unveiled in a specially designed building in 1905, the fiftieth anniversary of the siege.  It was damaged during the German siege of Sevastopol in 1942 and restored in the 1950s.

Siege of Savannah: The Siege of Savannah or the Second Battle of Savannah was an encounter of the American Revolutionary War in 1779.  The year before, the city of Savannah, Georgia, had been captured by a British expeditionary corps under Lieutenant-Colonel Archibald Campbell.  The siege itself consisted of a joint Franco-American attempt to retake Savannah, from September 16 to October 18, 1779.  On October 9 a major assault against the British siege works failed.  During the attack, Polish nobleman Count Casimir Pułaski, leading the combined cavalry forces on the American side, was mortally wounded.  With the failure of the joint attack, the siege was abandoned, and the British remained in control of Savannah until July 1782, near the end of the war.

Azemilcus, King of Tyre: Azemilcus ('zmlk\) was the King of Tyre during its siege by Alexander the Great in 332 BC.  Alexander had already peacefully taken Byblos and Sidon, and Tyre sent envoys to Alexander agreeing to do his bidding.  His response was to declare that he wished to enter the city to sacrifice to Melqart, known to Alexander as the Tyrian Herakles.  Azemilcus was with the Persian fleet at the time, and the Tyrians, unsure who would win the war, responded by saying that they would obey any other command but that neither Persians nor Macedonians could enter the city.  When Alexander finally captured the city, Azemilcus and various other notables, including envoys from Carthage, had taken refuge in the temple of Melqart, and Alexander spared their lives.

Siege of Bergen op Zoom (1588): The Siege of Bergen op Zoom was a siege that took place during the Eighty Years' War and the Anglo–Spanish War between September 23 - November 13, 1588.  The siege was between a besieged Anglo Dutch force under Thomas Morgan and Peregrine Bertie and a Spanish besieging force under famed commander Alexander Farnese, the Duke of Parma.  An English officer Grimstone claimed to be a disaffected Catholic had set up a trap during which a large Spanish assault was then bloodily repulsed.  An Anglo Dutch relief column under the command Maurice of Orange soon after arrived and forced the Duke of Parma to retreat, thus ending the siege.

Saladin: 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.  A Sunni Muslim of Kurdish ethnicity, Saladin led the Muslim military campaign against the Crusader states in the Levant.  At the height of his power, his sultanate included Egypt, Syria, Upper Mesopotamia, the Hejaz, Yemen and other parts of North Africa.

Siege of Tyre (332 BC): The Siege of Tyre was orchestrated by Alexander the Great in 332 BC during his campaigns against the Persians.  The Macedonian army was unable to capture the city, which was a strategic coastal base on the Mediterranean Sea, through conventional means because it was on an island and had walls right up to the sea.  Alexander responded to this problem by first blockading and besieging Tyre for seven months, and then by building a causeway that allowed him to breach the fortifications.
