The Treemen are all on high alert. A group of 20 Treemen bad been lose, telling the others of presence of powerful monsters, or a large tribes.
At the moment, no Treemen forage, all keeping an eyes on the surrounding. Some even look upward, in case the attackers come from above.
However, two days since the lose of the 20 Treemen cause the others to slowly lowered their guards. Their movement become less orderly, with some holes appearing in their patrols.
Considering they are tree-monsters, they are not fast, and they don't like moving, so they rarely do such an extensive patrols. When given the reason to not do so, they will just walk around, instead of doing the Treemen equivalent of running.
The monsters would have never suspected there is an intelligent mind behind the loss of the Treemen, which take them by surprise when the attack come without any warning.
