Set upon

I was set upon by a couple of young thugs.

O'Connell was walking with a friend when the pair was set upon by the teenagers. They beat O'Connell and knocked him to the ground.

With Gambier Bay and Hoel sinking and Roberts not much longer for this world, the Johnston is now set upon by four cruisers and a number of destroyers. The ship's crew patch holes as fast as they can, but the ship is literally gradually being taken apart by repeated salvos. The fact that this particular set of Japanese ships is STILL using armor-piercing instead of high explosive is the only saving grace.

On receiving the letter, I immediately set upon writing a reply.
