Helsreach - Did Grimaldus' standard bearer wear a helmet?

[Gendo]

Just a quick question brothers, was the standard bearer in the Grimaldus team described as not wearing an helmet?

[Sword Brother Adelard]

"Artarion licks his steel teeth. I hear him doing it, even though he wears his helm."

 

Found this in the ebook.

[Marshal Arthur]

He wasn’t wearing it when they stood on the walls, just before the battle joined, but Grimaldus ordered him to put it on before the fighting began. He wore it for the rest of the battle.
