Why is whittlesey weary about attacking argonne forest?

Whittlesey is wary about attacking the Argonne Forest due to the challenging terrain and the dense forests that provide ample cover for enemy forces, making it difficult for his troops to navigate and execute a successful assault. Additionally, he is concerned about the potential for heavy casualties and the risk of being outflanked or ambushed in such a confined and complex environment. The overall strategic implications of the attack also weigh on his mind, as a failed offensive could jeopardize the broader mission and the safety of his men.
