bag trap造句

• Because of their certainty, Polish commanders decided to make " the big bag trap " more shallow-which meant that it was less flexible, and Polish positions would be easier to crush if the defense was not successful ( as it happened )-but on the other hand-if the defense was successful ( which didn't happen since the unexpected direction and strength of the German main attack were deadly ), the shallow " bag " would be more effective because the German attack would be stopped faster and with greater casualties for the enemy due to a greater concentration of firepower.
