Dutch Naval Officer: Laurens Jacobszoon Alteras

Laurens Jacobszoon Alteras was killed near Gibraltar on 16 October 1622. He was a skipper in the merchant marine, prior to being in the army from 1597 to 1599. He commanded in the Battle of Gibraltar and replaced Vice-Admiral van Heemskerck in 1607. He was killed with convoying merchant ships when attacked by a Spanish squadron. He served the Admiralty of Zeeland. He was appointed as a captain at sea in 1605. He served as a temporary Vice-Admiral from 27 January 1607 to 20 August 1607. On 18 February 1618, he was appointed as a Vice-Admiral. This is based on my translation of the entry in Luc Eekhout's Het Admiralenboek. We also know that Laurens Jacobszoon Alteras commanded the Zeeland ship Aeolus in 1620.
