In the novel "Milkweed" by Jerry Spinelli, the characters Henryk and Kuba are Jewish boys living in the Warsaw Ghetto during World War II. To escape the dire conditions and danger of the ghetto, they develop a plan to climb over the ghetto wall and escape to the Aryan side of the city.
Henryk and Kuba's strategy involves using a pile of trash and debris that has been thrown over the wall as a makeshift ladder to climb over the wall. They also plan to wait until nightfall when the guards are less vigilant and the darkness can help conceal their escape.
However, their first attempt fails when they are caught by the guards and beaten. Undeterred, they try again a few nights later, this time with the help of an older man who agrees to distract the guards while they climb over the wall. The distraction works, and Henryk and Kuba are able to climb over the wall and escape to the other side.
Throughout their ordeal, Henryk and Kuba rely on their resourcefulness, determination, and courage to overcome the challenges they face in their attempt to escape the ghetto. Their strategy of using the pile of trash and waiting for the cover of darkness demonstrates their ability to adapt and think creatively in the face of adversity.
