Oriental Wooden block with writing and map- what is it?

[Fort Susquehanna]

I found this in a USN Grouping. Does anybody have any ideas on what it is? Thanks,

How big is it?

It is about 4" x 1 1/4"

is it a capture/surrender tag for a sword?

is it a capture/surrender tag for a sword?

 

That's what I was thinking. I have seen them in cloth and wood. Typically they had the name address of the person who surrendered the sword, expecting they'd get it back some day. In villages with nothing like street addresses, a map would be needed to show his home.

However, there don't seem to be any holes in the wood to attach it to a weapon.

maybe the hole is drilled lengthwise through the piece?

Anymore pics OP?

There are no holes. I wondered if the map was for a grave. Thanks for the ideas.
