Qoraal sii-socda faqradan - Bishii Abriil 1608 ka dib markii ay ka soo carareen Earl-kii (14kii Sebtember 1607), Sir Cahir O'Doherty oo ahaa kii ugu dambeeyay ee Gaelic Lord of Inishowen iyo hogaamiyaha mucaaradka ayaa go'doomiyay Magaalada Derry. Waxa uu ka cadhooday in dhulkiisa lagala wareegay beerista Ulster. Intii Sir Cahir uu isku dayayay inuu qabsado Derry wuxuu Sir Niall Garve O'Donnell u diray qalcadda Lifford si uu uga hortago isku day kasta oo Ingiriis ah oo ah inay ciidamo xoojin ah u diraan Derry iyagoo ka gudbaya webiga Lifford. Niall Garve oo aad u hanti badnaa wuxuu rabay in uu ku dhowaado ficilka si uu fursad ugu helo qayb wanaagsan oo ka mid ah boolida marka Derry la eryo. Halkii uu Lifford aadi lahaa wuxuu aaday Mongavlin Castle wuxuuna ka saaray Ineen Dubh. Halkaan wuxuu bilaabay inuu boobo aagga maxalliga ah iyo markii uu maqlay warka ku saabsan ficillada Niall Garve, Sir Cahir ayaa markiisa ka saaray Niall Garve oo dib u soo celiyay Ineen Dubh ee Mongavlin. Sir Cahir ayaa ugu danbeyntii soo saaray oo gubay Derry
waxaana dilay Guddoomiyihii Sir George Paulet. Wax yar ka dib qalcaddii ayaa laga tagay sababo la xiriira dagaalka dhexmaray qabiilka O'Donnell.
