On 28 June 1929 the Venezuelan rebel leader Rafael Simón Urbina attacked Curaçao and took several hostages amongst whom was the governor Leonard Albert Fruytier [nl] and the garrison commander Borren.
[1] After Urbina's attack, the Dutch government decided to station one naval ship ("stationsschip") in the Antilles permanently.
After World War II, the VKC and VKA were redesignated Antiliaanse Militie (ANTMIL) which still exists on Curaçao.
In December an artillery unit from the Dutch East Indies Army was sent to Aruba to improve the defences.
All soldiers were billeted near the oil refinery at Savaneta, the present location of the Marine barracks.
Later a Dutch battery on Curaçao engaged another U-boat when it attacked an oil tanker sailing off the island.
