"Right," George nodded at the plan Fred outlined. "I'll cover you from over there," he pointed to a massive tower of barrels on the opposite side of the dock. "I'll try to distract them while you get the Muggles out of the line of fire."
He started towards the barrels, moving quickly and dodging the wrecked luggage strewn about the dock. He was able to get to his position without being seen and quickly removed a couple of decoy detonators from his pocket and enlarged them. Glancing in Fred's direction, he tried to wait until his twin had reached the Muggles before lobbing the detonators in two different directions, away from both the Muggles and the Death Eaters.
As the identical wails of the detonators added their voices to the already noisy atmosphere one of the masked figures turned and spotted George. He ducked behind the barrel pile just in the nick of time as a curse went zinging by his head. "Just brilliant," he quipped to himself, "as if I can afford to lose more ears."
