The Second Larut War took place in 1865 and was sparked off by a gambling quarrel in June of that year between members of the two opposing secret societies. According to Parkinson in his book British Intervention in Malaya 1867-1877 the "Hysan or Tokong" leader in Penang was "Chan Keng Kwi", with "Lew Ah Sam" as leader in Larut. The Hai San members took 14 Ghee Hin as prisoners, 13 of whom were killed. Wikipedia
