The Letters of Robert Blake

The book edited by J. R. Powell entitled The Letters of Robert Blake, published by the Navy Records Society, has some useful details. For example, this book lists the ships assigned to Robert Blake's squadron at the Battle of the Gabbard. I believe that R. C. Anderson used this information for his article in the Mariner's Mirror about fleet lists in the First Dutch War. There is also important information about Blake's squadron that was pursuing the Royalists prior to the First Dutch War.
