You must bury him, as it's unclean for a clansman to bury another clansman who has taken their own life.
After the death of the head messenger, the District Commissioner and his men arrive in Oknowo's compound ready to arrest Okonkwo. Oberika leads them to Oknowko who In the end, committed suicide. Okonkwo had killed himself because he had failed to start a war between Umuofia and the missionaries. Oberika mourns his death as the District Commissioner and his men take down the body and get it ready for burial.
After they burn down the church Mr. Smith reports the aftermath to the District Commissioner, They call in the leaders of Umofia for a "meeting" Okonkwo who is one of the leaders suggest they bring their machetes just in case. this meeting turns out to be an ambush and the men are arrested and thrown in jail with a bond of 250 cowries. During their stay in jail, the men of Umofia are beaten and starved of basic needs.
HAHAHA, you savages will never make it out of jail.
Finding out that the Men of Umofia have been imprisoned they make up the number of cowries needed and the six men are released from jail. Okonkwo is traumatized and is filled with rage after what they did to him, as he was falling asleep the messenger rings about the village of a meeting tomorrow morning to discuss the situation, throughout the night Oknowo reflects upon his battle equipment of a war with the missionaries. the next day arrives and it is packed as the people of Umofia gather around to discuss what to do.
