The forest guards who had accompanied the 110-strong herd of jumbos, which had left a trail of death and destruction in three districts, up to the Kaziranga National Park (KNP), had breathed a sigh of relief too soon. Hardly had one week elapsed when the herd split and 70 per cent of the mammoths are wending their way back wreaking havoc in their wake. Yesterday night, 14 huts were destroyed at Dainigaon near Nimatighat.
