What is the author's tone in the memoir, There Was A Country?

There Was A Country by Chinua Achebe is written with the unique authority of one who has actually experienced what he is writing about. He lived in the Eastern Region of Nigeria which seceded from Nigeria and declared itself to be the independent Republic of Biafra. Chinua was raised a Christian by his devout parents but as he matured and became more curious and sophisticated, he was drawn to the old religion of his culture, the Igbo, and the poetry of their stories and legends
