The entry in Witte de With's journal for 31 May 1653

In an entry in Witte de With's journal for 31 May 1653, there is some interesting information, which I have annotated from Carl Stapel's paper:

The vice-admiraal Johan Evertsen was in the ship
of "Capt. Claes":
Adm    Ship          Guns Crew Captain
Z      Milde Maarten 26   110  Claes Jansz Sanger (with Johan Evertsen)
Mi-Dir Leeuwinne     30   120  perhaps the luitenant of the late 
                                   Johannes van Regermorter
