<prompt> Bhala okuqhubekayo kwalesi sigaba - Ekupheleni kweNkathi Ephakathi kwakhiwa izibhamu ezinkulu, ezinamandla, futhi zasakazekela emhlabeni wonke. Njengoba zazingasebenzi ekuqobeni izinqaba ezintsha ezazivela ekuthuthukisweni kwezikhali, izinjini zokuvimbezela - ezinjengezinqaba zokuvimbezela kanye nama-trebuchet - zasetshenziswa kancane. Kodwa-ke, izibhamu zamapulangwe zaba nendima efana neyemibhoshongo yokuvimbezela ngezikhathi ze-gunpowder, njengaleyo eyasetshenziswa ekuvinjezelweni kweKazan.  <response>: ngo-1552, eyayikwazi ukubamba izibhamu ezinkulu eziyishumi, ngaphezu kwezibhamu ezikhanyayo ezingu-50. Omunye umphumela ophawulekayo wezikhali zempi kule nkathi kwaba ushintsho ezinqabeni ezivamile. UNiccolò Machiavelli wabhala, Alikho udonga, kungakhathaliseki ukuthi lubukhulu kangakanani, olungenakucekelwa phansi izibhamu ezinsukwini ezimbalwa nje kuphela. Nakuba izinqaba zingazange ziphelelwe isikhathi ngokushesha ngenxa yezikhali, ukusetshenziswa kwazo nokubaluleka kwazo enkundleni yempi kwancipha ngokushesha. Esikhundleni semibhoshongo emikhulu nama-merlon, izindonga zezinqaba ezintsha zaziqinile, zinama-angle, futhi zikhotheme, kuyilapho imibhoshongo yayiphansi futhi iqinile; futhi kwakusetshenziswa umhlaba nezitini ezindongeni zezinqaba nasezindongeni. Lezi zindawo ezintsha zokuzivikela zaziwa ngokuthi izinqaba zezinqaba, ngenxa yesimo sazo esivelele esasizama ukuphoqa noma yikuphi ukuqhubekela phambili kuso ngqo emgqeni wokudubula wezibhamu. Eziningana zalezi zazinamabhethri ezinhlamvu, njengezinqaba zeNdlu kaTudor, eNgilandi. Ngokushesha izinqaba ezakhiwe ngezingange zathatha indawo yezinqaba zaseYurophu, futhi, ekugcineni, nezaseMelika.
