The ultimate proof can be seen of the first Vacquier then still written as Vaquie, who left for the Dutch East Indies.
Below is a text copied from EA Zonneveld, who I am grateful to have found this data.
Charles was the first Vacquier to set foot on Indian soil. A Frenchman (born in Bouches in 1794, he was probably called up in 1812 as an 18-year-old to serve in Napoleon's army.
In 1815 he witnessed the battle of Waterloo. After the defeat he (as well as thousands of French fellow sufferers)
near Brussels because a return to France was prevented by the French government.
Because King William I had also become king of the Southern Netherlands by the agreements of the Congress of Vienna (1815) and soldiers were needed in the Indies to build up an army (after the return of the colony by England), the French were allowed to " deserters” signed up for the replenishment army in the Indies from 1816.
In 1821 Charles signed in Harderwijk for an employment contract of 8 years and received a hand money of 10 guilders.
About 3300 Frenchmen took advantage of this arrangement between 1816 and 1821. After 1821 the French government did allow return and people no longer reported to Harderwijk.
On August 4, 1821 , he departed with 74 other soldiers (42 French, 14 Belgians, 16 Dutch, 2 Swiss and a Dane) and 4 officers with the frigate Marij and Hillegonda from Helvoet (present-day Hellevoetsluis) to the Indies.
The copper wooden three-masted ship was a fast-sailing ship that, according to advertisements in both the Rotterdamse and the Bataviasche Courant, was well equipped for the transport of passengers.
From 1821 to 1834 this ship sailed annually with the Rotterdam captain Hessel Glazener to the Indies.
The ship was probably waiting for a favorable wind in the Brouwershaven roadstead for a few days and then set course south for a trip around the Cape of Good Hope.
On the way, the ship was sighted twice, as later reported by the Rotterdamsche Courant. The first time was on 24 August off the English south coast, the second was near Java when the ship Clay, which had started its journey to Europe from Batavia, passed. Since no mutiny or other disturbances have been reported, it can be assumed that the journey continued without any problems. On January 7, 1822 they arrived in Batavia.
On the voyages to the Indies before 1830, many people on board died en route and in the first years in the Indies as a percentage of illness. One soldier died on this journey who was already ill on departure and 20 soldiers died in the first year in the Indies (1822). In the following three years another 20 men. Up to and including 1830, a total of 55 people died. 73% of the soldiers embarked in Helvoet did not receive their pension. In addition, 5 of the 75 persons turned out to be unsuitable for military service in the tropics shortly after arrival and returned to the Netherlands. The other 15 soldiers have retired.
After disembarkation in Batavia they walked to the barracks in Weltevreden to find out their final destination. Charles, who had served as a fusilier under Napoleon, became a hussar in the Dutch East Indies Army (later known as KNIL). He may have served in the Java War that raged from 1825 to 1830 in the Kedoe region (also called Kadoe)9 and which was so disastrous for the NIL in the beginning that Kon. Decision of 26/10/1826 that another expeditionary division of 3100 men (on top of the 1000 men of the replenishment army that year) was sent to the Indies. In this war 15,000 soldiers (7,000 Europeans and 8,000 natives) were killed, as well as 200,000 Javanese from war violence, hunger and disease.
Charles Vacquier (aged 25) lived in Kadoe in 1830, as the National Almanac of the Dutch East Indies indicated.
Because the Almanac only mentions European civilian men older than 16 years, the name
Vacqui (misspelled in the military studbook as well as in the Almanac) was only visible in 1830.
This is true because, according to a handwritten entry in the colonial studbook, Charles (35 years old)
(a kind of copy of the military studbook) retires (is passported) in 1830 and only then becomes a citizen.
In Kadoe, the Vacquier family branch was created by Charles Vacquier, who had at least 24 children by 4 women.
The first letter of the names he gave his children were in alphabetical order, with the exception of the
first child.
