The balloon slowly ascended again, airplanes circled the gray sky like dragonflies, it was the same for both sides.
At this moment, the battlefield was like a large chessboard, the no man's land in the middle was the border, the soldiers were positioned on both sides of the defensive line, the command posts were in the rear, along with guns and guards, all set up for a fierce battle.
Albert I looked at the balloons and airplanes rising from the German Army direction with some confusion. He asked, "The Germans clearly know Shire has already put machine guns on planes, sending up balloons is just asking to be destroyed, isn't it?"
"The Germans have no choice!" General Charles explained, "In such weather, only at balloon height can you see the flash of artillery fire from kilometers away. To counter the French artillery, they must face possible danger!"
"But how do they protect themselves?" Albert I looked incredulous, "This is no different from suicide!"
