The following are the continuation of excerpts/minutes of a Chief Obafemi Awolowo interview. What he said on Civil War, Twenty Pounds Policy, Starvation Policy are on my previous threads. I'll post a link to the video when i find it

CHANGE OF CURRENCY

And it is on record that Ojukwu admitted that two things defeated him in this war, that’s as at the day he left Biafra. He said one, the change of currency, he said that was the first thing that defeated him, and we did that to prevent Ojukwu taking the money which his soldiers has stolen from our Central bank for sale abroad to buy arms. We discovered he looted our Central bank in Benin, he looted the one in Port Harcourt, looted the one in Calabar and he was taking the currency notes abroad to sell to earn foreign exchange to buy arms.
So I decided to change the currency, and for your benefit, it can now be told the whole world, only Gowon knew the day before, the day before the change took place. I decided, only three of us knew before then- Isong now governor of Cross River, Attah and myself. It was a closely guarded secret, if any commissioner at the time say that he knew about it, he’s only boosting his own ego. Because once you tell someone, he’ll tell another person. So we refused to tell them and we changed the currency notes. So Ojukwu said the change in currency defeated him, and starvation of his soldiers also defeated him.
These were the two things that defeated Ojukwu. And, he reminds me, when you saw Ojukwu’s picture after the war, did he look like someone who’s not well fed? But he has been taking the food which we send to civilians, and so we stopped the food.
