Here is some info:

the only son of Ii Naochika and the daughter of Okuyama Chikatomo; he enter=
ed the service of Tokuagwa Ieyasu around 1578, and quickly distiguished hims=
elf as a brave fighter; he commanded 3,000 men at the Battle of Nagakute and=
did great damage to the ikeda troops he faced with gunnery fire; following =
the Tokugawa transfer to the Kanto in 1590, Naomasa was given Minowa Castle =
in Kôzuke province, worth 12.000 koku; at the start of the Sekigahara Campai=
gn, he participated in the attack on Gifu Castle and at the actual Battle of=
Sekigahara commanded 3,600 men; at Sekigahara he acted as an escort to Ieya=

Fukushima Masanori and attacking Ukita Hideie's contingent; at the end of th=
e battle he was shot and wounded by a Shimazu sniper; he was afterwards awar=
ded Sawayama in Ômi province but died in 1602, evidently as a result of his =
Sekigahara wound; he was noted from dressing his men in red armor, and his c=
