|In Operation Boleas, a South African military intervention force invaded Lesotho in September 1998, to restore law and order following an attempted coup.
On the morning of 22 September, during the initial invasion, four South African helicopters were sent to Katse, and landed on the ground near the small army garrison which guards the 185 metre high Katse Dam, the most important single component of the Lesotho Highlands Water Project.
Sergeant Jeremy Sax of Cape Town, not a Sesotho speaker, walked to the base unarmed to say that the intervention force was taking over the garrison. The soldiers inside told him that this was their responsibility, and that he should leave. When he did not do so, he was shot by them, and apparently died almost instantly. A medical doctor with the intervention force, Captain Johan Nel, went to the aid of Sergeant Sax, and was also shot dead. There was then an exchange of fire between the two sets of troops in which another South African soldier was wounded. The helicopters then took off, leaving their wounded comrade on the ground, and strafed the Lesotho Defence Force garrison. 16 out of 17 soldiers in the garrison were killed, there being just one survivor who was eventually taken for treatment at the trauma unit of the project at Motebang Hospital, Hlotse.
It is said that four other soldiers survived, simply because when the attack took place they had gone out jogging. When they returned nearly all their comrades were dead.
