Obviously, sieges (one force contesting control of a castle, fortress or fortified town or city,
against a force most of which stayed inside it) frequently lasted multiple days starting way
before then (perhaps as far back as recorded history?), but I'm not interested in those.
我想，更確切地說，我可以問： 點擊 美國內戰是否是第一場戰爭，至少有4次多日戰爭（不是圍攻）在10年之內發生，或者至少在1年內發生過3次多日戰爭（不是圍攻）？
