The fourth series of Blackadder sees him as a Captain in the trenches of World War One, with Baldrick as his dogsbody. In "Captain Cook" Blackadder volunteers to be a war artist. In "Corporal Punishment" he faces the death squad after killing a pigeon. In "Major Star" he has to put on a Music Hall show. In "Private Plane" he volunteers to be trained as a pilot by Rik Mayall. In "General Hospital" he has to uncover a spy in the wardrooms. In "Goodbyeee" the final big push is looming too close for comfort.
