Dutch Captain: Christiaan Eldertszoon

Christiaan Eldertszoon served the Admiralty of the Maze (Rotterdam). He commanded the Wapen van Utrecht in the Battle of Lowestoft in June 1665. He was assigned to Jan Evertsen's Second Squadron. In this battle, the Wapen van Utrecht carried 36 guns and had a crew of 163 men. About 18 August, he was with De Ruyter's fleet and in De Rutyer's squadron. That list gives the name of his ship as the Utrecht (36 guns, a crew of 110 sailors, 10 marines, and 20 soldiers). On about 21 August, he was operating under the command of Vice-Admiral van Nes, which is plausible, as he may have been in van Nes's division in De Ruyter's squadron. The 18 August list includes van Nes in De Ruyter's squadron. Vice-Admiral van Nes flew his flag on the Rotterdam (built in 1658, with 46 guns, a crew of 189 sailors, 9 marines, and 30 soldiers). On 13 September 1665, he was assigned to De Ruyter's First Squadron. Sources:
