Noted for his bravery under fire he served two tours of duty with the Biafran Army, rising to the rank of major, and was the last white mercenary to leave the country as secession ended. Williams found his Biafran troops to be completely different from those whom he commanded in
Katanga. "I've seen a lot of Africans at war," he was quoted as saying. "But there's nobody to touch these people. Give me 10,000 Biafrans for six months, and we'll build an army that would be invincible on this continent. I've seen men die in this war who would have won the
Victoria Cross in another context". An irascible man, he was known for constantly screaming at his men and threatening to kill them if they did not obey his orders with a
Time correspondent in 1968 observed him to shout at his troops: "You rotten bastards! You bloody, treacherous morons!". Williams was known in Biafra as being "bullet proof" due to his ability to survive multiple wounds and was five times reported to be killed in action between December 1967-October 1968, only for him to turn up alive. Completing his first contract and following a brief stay in the UK, Williams returned to Biafra on 7 July 1968. He was assigned to the 4th Commando Brigade led by Lt. Col
Rolf Steiner. Steiner had command of 3000 men, and was assigned to the area around the
Enugu -
Onitsha road. Williams, who liked to joke that he was "half-mad", would personally lead his troops into battle, sometimes standing in a hail of Federal gunfire, just to prove to his troops that he was indeed "bullet-proof". His resolve under fire would often unnerve the more superstitious of Nigerian soldiers and serve to rally his own. On 24 August 1968 Williams was drawn into a critical battle of the conflict. At this point, he had 1000 soldiers under his command which carried out counteroffensives against two battalion-sized enemy units attempting to cross the
Imo River Bridge with Soviet military advisers. When Williams returned to Aba for additional ammunition to continue the fight, he was told that there was simply none to be had. The Nigerian Air Force had become quite successful in blocking supplies into the beleaguered state. Some of Williams' men had only two rounds left for their rifles and many were forced to withdraw. Following the arrest and expulsion of Steiner and four others, Major Williams was allegedly the only European still left serving with the Biafran army. He left the state shortly before its collapse. It is thought that Williams, who encountered author
Frederick Forsyth there as a war correspondent, served as the inspiration for the character of Carlo Shannon in Forsyth's
The Dogs of War. == Afterward ==
