In the run-up to the battle at Charm, the Lady lets the Captain recruit from among the Guard to bring the Company's strength up to 1,000. Less than 200 became the core of the White Rose's rebellion. Less than a dozen went south after the Dominator was defeated, including Lady. Somewhere between fifty and a hundred entered Taglios. About 10,000 soldiers crossed from Hsien under Sleepy's command, though fewer than 1,000 were sworn brothers of the Black Company; I'm not sure how many returned under Survin's command.
