On his arrival he found that conditions and European opinion were becoming more instead of less unfavourable for Indians, and though in 1906, when the native rebellion broke out in Natal, he again offered and secured the acceptance of an Indian Stretcher-Bearer Corps with which he again served and received the thanks of the Governor, he gradually found himself driven into an attitude of more and more open opposition and even conflict with Government by a series of measures imposing more and more intolerable restraints upon his countrymen.  It was in 1906 that he first took a vow of passive resistance to a law which he regarded as a deliberate attack upon their religion, their national honour, and their racial self-respect.  In the following year he was consigned, not for the first time, to jail in Pretoria, but his indomitable attitude helped to bring about a compromise.  It was, however, short-lived, as misunderstandings occurred as to its interpretation.  The struggle broke out afresh until another provisional settlement promised to lead to a permanent solution, when Mr. Gokhale, after consultation with the India Office during a visit to England, was induced in 1912 to proceed to South Africa and use his good offices in a cause which he had long had at heart.  Whether, as Mr. Gokhale himself always contended, as a deliberate breach of the promise made to him by the principal Union Ministers, or as the result of a lamentable misunderstanding, measures were again taken in 1913 which led Mr. Gandhi to renew the struggle, and it assumed at once a far more serious character than ever before.  It was then that Mr. Gandhi organised his big strikes of Indian labour and headed the great strikers’ march of protest into the Transvaal which led to the arrest and imprisonment of the principal leaders and of hundreds of the rank and file.  The furious indignation aroused in India, the public meetings held in all the large centres, and the protest entered by the Viceroy himself, Lord Hardinge, in his speech at Madras, combined with earnest representations from Whitehall, compelled General Smuts to enter once more the path of conciliation and compromise.  As the result of a Commission of Inquiry the Indians’ Relief Act was passed, and in the correspondence between Mr. Gandhi and General Smuts the latter undertook on behalf of the South African Government to carry through other administrative reforms not actually specified in the new Act.  Mr. Gandhi returned to India just after the outbreak of the Great War, and the Government of India marked its appreciation of the great services which he had rendered to his countrymen in South Africa by recommending him for the Kaisar-i-Hind gold medal, which was conferred upon him amongst the New Year honours of 1915.
