How does gulliver happen to reach the island of brobdingnag? What happen to him when he reaches them?

Gulliver returns to the sea in a ship named Adventure.They continue on their journey for several months until a storm begins to brew, pushing the Adventure several miles off track. On June 16, 1703, the crew sees land and drops anchor, at which point the captain sends a dozen men on shore to fetch water. Gulliver wanders off and the ship leaves without him. He is "seized by one of the Natives, and carry'd to a Farmer's House."
