Wild Geese
The manga "Hellsing" features a band of mercenaries known as The Wild Geese, led by Pip Bernadotte. It is unclear whether the mercenaries are intended to be representing the same group as in the Daniel Carney novel, though this is possible. It is also likely that the group takes its name from The Wild Geese, the Irish who left Ireland following the Treaty of Limerick, since it was the Wild Geese serving France who finally broke the back of the English army at the Battle of Fontenoy in 1745.
