It turned out—much longer than I hoped. Our anti-tree squads were effective, but slow. They were cutting thousands upon thousands of trees by hand. Their numbers were large, but not large enough, and reinforcements took their sweet time to gather.
At least they didn't suffer losses. Besides the cold—which they were immune to—the mountains were an almost safe place. Most of the dangerous creatures either didn't live there or had already died from the ice-hole trees.
By the estimates of my Advisers, in a month, there will be enough ice-hole tree wood in the Bee Empire to give basic prosthetics to everybody who needed them. Craftsmen Bees have already started the work on them. Tabletina's Physicians used the experimental knowledge they gathered from earlier prosthetic implanting to write instructions and guides about ice-hole wood prosthetics to bees all over the Empire.
