Obasanjo, who made the revelation in Lagos yesterday said he had to ensure that his orders were not disclosed to Biafran soldiers.
He alleged that his initial order was discovered by Biafran soldiers who hampered them during their move on the battle field.
According to Obasanjo, “It is a war we should never have fought and I have said that I have fought wars too many and I hope I will not witness another war in Nigeria again.
“From coup and counter-coup, we rolled on to civil war.
“The initial push petered off by the time I went to the war front.
“The first things I learnt were the errors committed by my predecessor; and the next thing is how do we push up the order that I gave?
“I followed the book strictly by the time I had written it.
“A copy was in the hand of the Biafra organisation for freedom.
“When we moved, we were seriously hammered.
“The final push in 1969, my order was not typed; it was in my pocket to ensure that nobody had a copy.
“That ended it. Nobody on the other side got to know what we were doing.”
Similarly, Obasanjo, had revealed why former Head of state, General Yakubu Gowon, was overthrown in a bloodless coup on July 29, 1975.
