William Allison Sweeney,
History of the American Negro in the Great World War
“ Henry Johnson! That Henry, once a mild-mannered chauffeur, who to protect his comrade, Needham Roberts, waded into a whole patrol of 'bush Germans' with a lot of hand grenades, his rifle and his trusty 'steel' in the shape of a bolo knife, and waded into them so energetically that when the casualties were counted there were four dead foemen in front of him, thirty-four others done up so badly they couldn't even crawl away, and heaven knows how many more had been put to flight. ”
