Jyn didn’t see who threw the first grenade. She heard it strike pavement despite the noise of the vehicles, recognized the sound despite the murmuring from the rooftops and the sharp commands of the stormtroopers. A glint of sunlight drew her eye to the metal sphere and she saw it bounce once, roll half a meter in the direction of the tank, then disappear in an eruption of street fragments and smoke and shrapnel. She felt the resonant boom in her teeth. She heard a dozen cloaks and overcoats being shucked in unison, then the dull clack of pistols and rifles being brought to bear.
