The Duration of the strike!

Tens of thousands of workers were out on strike from the East to the West Rand; the Smuts regime had formed a special committee of Cabinet Ministers to deal with the situation; and thousands of police mobilised and drafted to the area.
They dealt with it by means of bloody violence. The police batoned, bayoneted and fired on the striking workers to force them down the mine shafts. The full extent of police repression is not known but reports from miners and some newspapers reveal intense persecution and terror during the week following Monday, 12 August.
A peaceful procession of workers began to march to Johannesburg on what became known as Bloody Tuesday, 13 August, from the East Rand. They wanted to get their passes and go back home. Police opened fire on the procession and a number of workers were killed. At one mine workers, forced to go down the mine, they then started a sit-down strike underground. The police then drove the mineworkers back up to the surface, they then started beating them up, chasing them into the veld with baton charges.
In protest against these savage brutalities, a special conference of the Transvaal Council of Non-European Trade Unions (CONETU) decided to call a general strike in Johannesburg on Wednesday, 14 August. The Johannesburg City Council sent a deputation to plead with CONETU to maintain essential services. Many workers heeded the call, but the weakness of the unions generally, and the failure to bring the call home to the workers in factories, resulted in only a partial success of the strike.
CONETU called a mass meeting of workers at the Newtown Market Square on 15 August. The meeting was banned in terms of the Riotous Assemblies Act, and the decision banning the meeting was conveyed by a senior police officer, backed by a large squad of armed police. Those present were given five minutes to disperse. Only quick action by people's leaders who went among the angry crowd averted a massacre.
By Friday, 16 August, the amount of striking workers reached the 75,000 mark according to the government.
Throughout the week hundreds of workers were arrested, tried, imprisoned or deported. Leaders of the African trade unions and the entire Executive Committee of the African Mine Workers` Union, the whole of the Central Committee of the Communist Party and scores of Provincial and local leaders of the African National Congress were arrested and charged in a series of abortive "treason and sedition" trials. Innumerable police raids, not only in the Transvaal but in all the main cities in the country including Durban, Cape Town, Port Elizabeth, Kimberley and East London, were carried out on the offices of trade unions, the Congresses and the Communist Party. The homes of leaders of the ANC, the Communist Party, the Indian and Coloured Congresses and the trade unions were also raided simultaneously. The white South African State was mobilised and rampant in defence of its cheap labour policy and big dividends for the mining magnates and big business. This marked the opening of a phase of intense repression by the racist regime of the day, led by Field Marshal Smuts, against the forces for change in South Africa. This repression continues to this day under the Vorster regime.
The African Mine Workers` Union, mainly because of the very difficult circumstances under which it operated, was never a closely-organised well-knit body. During the strike the central strike committee was effectively cut off from the workers at each mine by massive police action and the workers had to struggle in isolation. They were continually told that all the other workers had gone back to work, and apart from Union leaflets hazardously brought into the compounds by gallant volunteers - a large number being caught and arrested - there was no system of interchanging information.
Nevertheless, thousand of miners defied terror, arrest and enemy propaganda and stood out for five days - from 12 to 16 August. During the strike 32 of the 45 mines on the Rand were affected according to one report received by the Union and later confirmed by the Johannesburg Star. According to the estimates issued by the Chief Native Commissioner for the Witwatersrand, 21 mines were affected by the strike, 11 wholly and 10 partially. The dead, according to this official, numbered nine, of whom four were trampled to death, three died in the hospital, one was shot dead and one "killed himself by running into a dustbin".
The regime called the strike a failure. But no great movement of this character is really a "failure", even though it might not succeed in its immediate aim.
