How successful was jonas's final rebellion against his community in chapter 21-23

Instead of waiting two weeks as he and the Giver had planned, Jonasis forced to escape right away. At the evening meal, his father  tells the family that he tried to see if Gabriel could sleep through the night at the Nurturing Center, and that the newchild had cried all night. The staff, including Jonas’s father, voted to release him the next day. Jonas cannot allow this to happen, so he takes some leftover food and his father’s bicycle, which has a child seat, and leaves, relying on his own courage and strength instead of on the memories that the Giver had promised. Jonas has broken serious rules against leaving his dwelling at night and taking food. After riding all night, he and Gabe rest during the day, hiding from the planes that fly overhead searching for them. He transmits memories of exhaustion to Gabriel in order to make him sleep during the day, and in order to avoid the heat-seeking technology of the planes, he transmits memory of intense cold to both of them so that their body heat does not show up on the planes’ devices. After several days, when Jonas and Gabriel have left all communities far behind, the planes come less frequently.

If you are reading the giver its real easy to see that Jonas is successful and accomplished his mission.
