The warriors and mechas originally stationed at the position have already retreated to the new defense line behind. And because the enemy broke through both flanks, this position held no strategic value and was completely ignored. Fatty chose to hide here because, in addition to the large amount of mecha wreckage and deep trenches that provided cover, it also allowed him to observe the gathering of Reinhardt's Armored Division.
Deciding to voluntarily abandon the position to shrink defenses was a decision made by Fatty, as Reinhardt had committed so many forces in this direction—too many to eliminate.
In this situation, Fatty chose without hesitation to trade space for time.
Douglas required three days, didn't he? Fatty gritted his teeth and decided to hold the Long Line Ridge for those three days. During these three days, four Infantry Divisions and one Armored Division of the Freedom Front would resist under his command.
