The commission was followed by an investigation led by a more powerful authority, the commissioners of accounts. They met at Brooke House, Holborn and spent two years scrutinising how the war had been financed. In 1669, Pepys had to prepare detailed answers to the committee's eight "Observations" on the Navy Board's conduct. In 1670, he was forced to defend his own role. A seaman's ticket with Pepys's name on it was produced as incontrovertible evidence of his corrupt dealings but, thanks to the intervention of the king, Pepys emerged from the sustained investigation relatively unscathed.
