What happened to gulliver when he escaped from the island brobdingnag

Gulliver wants to leave Brobdingnag. By chance, during a trip to the seashore, a giant eagle picks up Gulliver's traveling box and flies off with him. Realizing that the box is not edible, the eagle drops it into the sea. After some time the box is picked up by a passing ship of Gulliver's normal proportions. Gulliver finds it very difficult to adjust to the size of things back in England.
