The numbers staggered her. She had had no idea there were so many werewolves under Greyback, let alone all in one place. Seven of the adults looked to be over the age of sixty and were likely not to be effective field operatives (although Hermione knew little about the capabilities of elderly werewolves, so she put a pin in that) and the eldest of the children looked to be about thirteen, probably too young to be a reliable fighter (though she was putting a pin in that as well). If everyone here was a werewolf, Greyback’s pack strength was a minimum of sixteen.
