浯嶼是位處泉州和漳州府交界的海中小島，水道四通八達，為廈門、同安澄等地的海上門戶，故早在明代初年在此島立海軍基地的「水寨」，是福建海防的重鎮之一。後來，明政府不深思前人設水寨於浯嶼的意思，而將水寨向內遷移入廈門港，此一放棄浯嶼不智的舉動，是構成明世宗靖年間盜盤據浯嶼為巢的先決條件，而浯嶼島擁有優越的地理特質，則是誘引海盜前來巢據該島的另一項條件。 做為盜巢窟的浯嶼，和其他幾何島的賊巢相似，都擁有地形和位置上的特殊優救，發擇盜在遂行其目的時需之功用。除此，棲在閩離島時的海盜，除對巢窟周遭保原高度的警戒，經常維持人員「一半在巢，一半在船」的狀態，以分其風險，避免造成人員「全軍覆沒」的可能。另外，海盜也會在鄰近地區挑選合適的地點，以供他們在轉進或是逃竄時做為另一個巢窟之用，而這樣的點常不止一個，用「三窟狡兔」來形容這些海盜，應該是貼切的。

Wu Isle is a small island in the south of Fe-Chen. Because of the importance of its strategic position, early in the Ming dynasty a naval base was constructed here. However the latter Ming Government did not recognize the reason why the naval base was set up, so it moved this base backward to Port Xiamen. This measure giving up Wu Isle is similar to other piratical nests. Because it is another factor that Wu Isle in possession of excellent geographical character. Wu Isle is similar to other parasitical nests, because they all have geographical and positional advantage. In order to reduce the risk and exercise great caution, the pirates often kept a half in nest, the other on ship. Besides the pirates also found several suitable locations nearby, so that those locations could be another nests when the pirates were wanted.
