The Mission by Frederick Marryat

They had scarcely gained the wagons before the thunder and lightning became incessant, and so loud as to be deafening. It appeared as if they were in the very center of the contending elements, and the wind rose and blew with terrific force, while the rain poured down as if the flood-gates of heaven were indeed opened. The lightning was so vivid, that for the second that it lasted you could see the country round to the horizon almost as clear as day; the next moment all was terrific gloom accompanied by the stunning reports of the thunder, which caused every article in the wagons, and the wagons themselves, to vibrate from the concussion. A large tree, not fifty yards from the caravan, was struck by the lightning, and came down with an appalling crash. The Caffres had all roused up, and had sheltered themselves under the wagons.

The Hottentots had also begun to move, but had not yet recovered their senses -- indeed, they were again stupefied by the clamor of the elements. The storm lasted about an hour, and then as suddenly cleared up again; the stars again made their appearance in the sky above, and the red tinge of the horizon announced the approach of daylight. When the storm ceased, our travelers, who had not taken off their clothes, came out from their shelter, and met each other by the side of the extinguished fire.
