The last stand of HMS Thunder Child. To summarize, as a horde of people are shoving and pushing to escape to safety on a steamer, Tripods bearing down and ready to slaughter them all. From nowhere, the Thunder Child roars into life and charges straight at the Tripods, bringing down two down with torpedo tubes and heavy guns. This earns it a barrage of heat rays, and it just keeps going, trying to ram a third and take that one down as well, before succumbing and vanishing under the waves, saving everyone on the steamer. This from the Jeff Wayne musical really sums up how freaking awesome this whole bit is.
The scene is so awesome, it adorns the record cover◊ of the Jeff Wayne version.
First time the humans takes down a tripod. Five Martian tripods attacks the town of Shepperton, there the British Army has put up defense lines with their artillery, and one of them goes near the river harbour, there a massive gathering of refugees was waiting for ships to take them away from the battlefield, and it seems that it's about to unleash its ray gun at the people when the artillery hits it right on and turn it into Swiss cheese. Cue massive cheers from the protagonist and every human around him. Thought the cheerfulness disappears as soon it comes when the other Martians does a Roaring Rampage of Revenge on the humans, but their loss was enough to give the British Army time to prepare itself for future attacks.
The war machines! They're totally indestructible, and even an atomic bomb fails to put so much as a scratch on them. The ship design may be a bit dated today, but you can't help being a little impressed.
The first battle is especially impressive. The order to fire is given and the war machines are standing imperiously as all the bombs and bullets hit their force fields uselessly. Even the heat rays are swaying back and forth as though the war machines were looking around at the puny forces with contempt. "Oh, this is all you've got?" they seem to say right before they unleash their own weapons.
