There is actually more information on Nobunaga's human side. The information comes from Neil McMullin's Buddhism and the State in Sixteenth-Century Japan, p. 84. There are two examples.
In 1572, Matsui Yukan was sick with a tumor and Nobunaga sent help. On February 6, 1572, Nobunaga ordered doctors from Kannonji in Omi to quickly depart to Azuchi to treat Matsui Yukan.
Another example deals with a foot soldier. After a battle in 1573, Nobunaga noticed one of his foot soldiers feet was bare and covered with blood. Nobunaga then took a pair of sandals from his waist and gave it to bloodied foot soldier. The sandals were a lucky charm of sorts for Nobunaga since he carried with him into battle.
