Passage: In 1710, the Swedish army in Poland retreated to Swedish Pomerania, pursued by the coalition. In 1711, siege was laid to Stralsund. Yet the town could not be taken due to the arrival of a Swedish relief army, which secured the Pomeranian pocket before turning west to defeat an allied army in the Battle of Gadebusch. Pursued by coalition forces, the Swedish army was trapped and surrendered in the Siege of Tönning. In 1714, Charles XII returned from the Ottoman Empire, arriving in Stralsund in November. In nearby Greifswald, already lost to Sweden, Russian tsar Peter the Great and British king George I, in his position as Elector of Hanover, had just signed an alliance on 17 /28  October. Previously a formally neutral party in the Pomeranian campaigns, Brandenburg-Prussia openly joined the coalition by declaring war on Sweden in the summer of 1715. Charles was then at war with much of Northern Europe, and Stralsund was doomed. Charles remained there until December 1715, escaping only days before Stralsund fell. When Wismar surrendered in 1716, all of Sweden's Baltic and German possessions were lost.

Passage: Following a preliminary bombardment, the battle for Cebu City began on March 26, 1945, when the Allies launched Operation Victor II. Staging out of Leyte, where they had conducted rehearsal landings two days earlier, a large flotilla of cruisers and destroyers from the United States Seventh Fleet's Task Force 74 escorted the Cebu Attack Group to the island. Under the leadership of Major General William H. Arnold, the forces assigned to the operation consisted of the Americal Division's 132nd and 182nd Infantry Regiments, totaling about 5,000 men, were landed on Cebu island at Talisay Beach, 4 miles  southwest of Cebu City. The 182nd came ashore southwest of the city, while the 132nd landed at a wide gravel beach to the northeast opposite a palm grove. Meeting no Japanese opposition, the U.S. forces nevertheless suffered heavily from mines and booby traps as they crossed the beach.

Passage: Superferry 14 was a large ferry destroyed by a bomb on 27 February 2004, killing 116 people in the Philippines' worst terrorist attack and the world's deadliest terrorist attack at sea. On that day, the 10,192 ton ferry sailed out of Manila with about 900 passengers and crew on board. A television set filled with 8 lb.  of TNT had been placed on board. 90 minutes out of port, the bomb exploded. 63 people were killed instantly and 53 were missing and presumed dead. Despite claims from terrorist groups, the blast was initially thought to have been an accident caused by a gas explosion. However, after divers righted the ferry five months after it had sunk, they found evidence of a bomb blast. A man called Redendo Cain Dellosa admitted to planting the bomb for Abu Sayyaf. Six suspects were arrested in connection with the bombing while the masterminds, Khadaffy Janjalani and Abu Sulaiman, were killed.
