Because as long as Ike did it himself, it didn't matter even if Jones did not leave his shelter.
However, the first problem Ike had to solve at present was how to leave Milford without being discovered by the guards beside him.
Moreover, not only did Ike need to leave, but the drivers of Ike's group also needed to retreat from here safely.
However, soon, Ike came up with a solution.
"Hey, guys, you move these trucks a little back later and then close the curtains in the cab. Make sure that the guards on the sentinel tower are not sure whether there is anyone in our car. After parking the cars, you all get out of the cars and hide in the bushes over there, waiting for my later order!"
Then, Ike instructed the drivers of his convoy.
Then, Ike turned around and walked toward the sentinel tower.
