The question may refer to a fictional or alternate history scenario not covered by the provided materials.
Step-by-step explanation:
The date of the Second War of L'Manburg, November 16th, is not set by any of the historical events mentioned in the provided references. The references discuss distinct events: the fall of Anarch's kingdom in February 1738, the German Revolution in November 1918, the first battles of the American Revolution on April 19, 1775, the Americans who fought in the War of 1812, and an Anglo-French invasion with a cease-fire on November 7 on an unspecified year. None of these details pertain to the Second War of L'Manburg.
It appears that this question may be related to a fictional or alternate history scenario that was not provided in the references. The Second War of L'Manburg, with the specific date of November 16th, does not correspond to a verifiable historical event based on the given materials, therefore an accurate answer cannot be provided without the correct context.
