While most of the Military Department's activities are documented, the picture is more completely drawn during war periods. The records of Oregon's Indian wars-Cayuse (1847-1850), Rogue River (1855-1856), Modoc (1872-1873), Nez Perce (1877) and Bannock (1878) are particularly interesting.
Although both cruise ships are visually similar, there are a few differences between the two, depending on quantitative things such as size, cost and onboard facilities. The major difference between Allure of the Seas and Oasis of the Seas is that the former is 50 mm (2.0 in) longer than the latter. Moreover, Allure of the Seas started its maiden voyage on December 1, 2010. On the other hand, the maiden voyage of Oasis of the Seas started on December 5, 2009. Cost is another quantitative difference between the two cruise ships.
The success of the first two Oasis-class ships led Royal Caribbean Cruises to order a third ship of the type in December 2012. Harmony of the Seas was floated out on 19 June 2015, began her first sea trials on 10 March 2016, and was delivered to Royal Caribbean on 12 May 2016. After a construction time of 32 months, the ship first set sail on 15 May 2016 from the STX France docks in Saint-Nazaire, viewed by some 70,000 people.
