the downfall of uccala came in december 1111 as a result a conspiracy, and after a prior attempt by sussala to overthrow him. sussala was not in the vicinity at the time that uccala was murdered but within days had attempted a hazardous winter crossing over the mountains to srinagar. foiled by the winter weather on this occasion, he was able a few months later to venture once more and he proceeded to take control of kashmir from a half-brother, salhana. salhana had himself taken the throne after the briefest of reigns by radda, one of the leaders of the conspiracy against uccala, whose rule lasted a single day. it was gargacandra who organised the defeat of the conspirators and it was he who installed salhana, using him as a puppet for the violent four months until the arrival of sussala, a period which kalhana described as a "long evil dream".
