Looking for a warrior monk image.

Hi, I'm looking for an image I remember seeing in a book once. It was
of a group of warrior monks running along a beach, I think, with a
wide assortment of polearms held up. I believe one was a large war
axe, an ono I think. The other polearms may have been similar to the
weapons that were supposed to be carried by Benkei. If anyone can
provide me with information about this painting or an image it would
be greatly appreciated. Thanks.

Sincerely,

Isaias
