Definition of "spoilless"

Now and then a gaudy peacock would run from his shelter in the lauhala trees, but no wild boars came out, so we returned from our raid bloodless and spoilless.

1892, Rev. Herbert Henry Gowen, The Paradise of the Pacific, page 129

The absence of Kallisto and the spoilless return from the hunt go hand-in-hand, and they are elegantly combined with the return of Apollo to Leto.
