"yes,god knows things have gone downhill with me",he said.You should not have resigned from regiment,"said the iron master". That was the mistake. If only i had still been in the service at the time,it never would have happened.

Dear Student,
I am assuming that you have asked for reported speech. Given below is the answer for the same.

He answered in the positive that God knew things had gone downhill with him. The Iron master said that he should not have resigned from regiment. He replied that it was the mistake and wished that if only he had still been in the service at the time, it never would have happened.

If your query is different, please post again clearly in a new thread along with the instructions in order to make answering easier.

Regards.
