When and why did the author say that civil disobedience had triumphed for the first time in modern India?

Gandhiji visited Champaran to look into the problems of the poor peasants. There, he was greeted by thousands of peasants. This was the beginning of the peasant liberation from fear of the British. A peasant had been maltreated in a village called Motihari. Gandhiji set out to see him. The police superintendent’s messenger overtook him and ordered him to return. Gandhiji complied. At home, he was served an official notice to leave Champaran. Gandhiji signed the receipt and wrote on it that he would disobey the order. This was the beginning of Civil disobedience. Gandhiji again received a summon to appear in court the next day. The peasants thronged the courtroom. They wanted to help the ‘Mahatma’ who was in trouble with the authorities for trying to help them. The officials were powerless. Gandhiji helped them regulate the crowd. This shocked the officials. The magistrate postponed announcing the sentence by two hours and asked Gandhiji to furnish bail. Gandhiji declined. The judge released him without bail. The judge said he would not deliver the judgment for several days. Later, the case was dropped by the Lt. Governor himself. This way the Civil disobedience had triumphed.
