Saturday morning is "a most unexceptional morning" (1.9.4). The narrator talks to the milkman and his neighbor, and everyone is sure the military has all this under control.
Everything seems very ordinary, especially with the little touches that Wells adds, like the neighbor giving the narrator some strawberries from his garden.
The narrator ends up chatting with a bunch of sappers (think "soldier engineers") who generally agree with the neighbor and the milkman – they've got the situation under control. The sappers all have different theories about how to kill the Martians.
The narrator tries to get more info on the situation, but the newspapers only have old news (and not entirely accurate news at that).
The military prepares to confront the Martians, and the narrator's schoolboy dreams of heroic war are awoken by all this: "My imagination became belligerent, and defeated the invaders in a dozen striking ways" (1.9.21).
Then, while the narrator is having tea with his wife, some nearby towers catch on fire and the narrator's chimney is destroyed by the Heat-Ray. The narrator quickly decides that, rather than heroically defeat the Martians, he should just get out of town.
The narrator decides to go to Leatherhead, where he has family. The narrator runs over to the Spotted Dog in order to hire the landlord's horse and cart.
There's some miscommunication at the Spotted Dog, but the narrator successfully hires the cart and loads up his wife and servant and some of their possessions.
A passing soldier says something about the Martians "crawling out in a thing like a dish cover" (1.9.41).
And then the narrator is off. Apparently, he doesn't like dish covers.
