The operation was executed by undercover agents of the Military Intelligence Unit going into the Southside Community and infiltrating the Southside's' "POW Posse" which was a local gang operating in the area led by the now assassinated Franklyn Allen aka "Chubby Dread". There were fourteen men in this gang who were originally targeted for assassination. The men were promised jobs as drivers and bodyguards. The men, needing the arms and funding, agreed; and in the early hours of 5 January 1978, an army ambulance driven by an MIU operative, and a minivan picked them up at the intersection of Higholborn Street and Port Royal Street, then headed west towards Port Henderson, Saint Catherine where the Green Bay artillery range is located. On arrival at the Military Base, the men were led out to a section of the range where they were given strict instructions not to move as they would be picked up by other persons who would take care of their work requirements and supply them with arms to be transported into Kingston.. As soon as the MIU operatives drove off, a specially selected team of snipers from the JDF, led by Major Ian Robinson was lying in ambush in the nearby hills. The soldiers were armed with L8 General Purpose Machine Guns (GPMG),
L2A2 Self Loading Rifles and Sterling Sub-Machine Guns with
Browning 9mm pistols as sidearms. On the receipt of a pre-arranged signal from one of the MIU operatives which was the firing of a single shot from his
Browning 9mm pistol into the upper torso of Winston Hamilton aka "Saddle Head", the sniper team opened fire on the group of men from their nest in the hills. Five men fell dead under the hail of gunfire that erupted and the remainder fled into nearby bushes. At least one member, (Delroy Griffiths) entered the bay and was rescued by a passing fishing boat. Those killed were all Labourites from South Side: • Norman Thompson aka "Gutto", age 27, a former national footballer for SANTOS football team • Glenroy Richards,age 29, an aspiring reggae singer • Trevor Clarke, age 26, a labourer. • Winston Hamilton aka "Saddle Head", age 30, a contractor. • Howard Martin, age 19, a labourer. ==Aftermath==
