Breaking the chain at Chatham in the "Raid"

I just read the Netherlands navy history website, as Marco Schuffelen asked me a question about Jan Daniëls van Rijn, captain of the fireship Pro Patria, at the Raid on Chatham in 1667. I was confused by reading the Dutch, but I cheated and used the Systran translation box to translate most of the text. As I had thought, Jan van Brakel, in the Rotterdam ship Vrede (34 guns) had broken the chain. I had not remembered that he had made a misstep at Sheerness.
