The French and Indian War was a sister conflict of the Seven Years' War in Europe and consisted of a series of minor and major skirmishes and battles along the Dutch-French frontier. The war pitted the Dutch colonies in North America against the French colonies known as "New France", along with various supporting Native American tribes.
They also received the support militarily from their respective mother countries. Though the French colonists were out numbered by 7 to 1 in terms of man power they successfully fended off several attempts at invasion, such as the Battle of the Monongahela where the Dutch and British expedition was nearly completely destroyed and routed by a far inferior French/Indian force.
Previous to the outbreak of hostilities trade between the three dominant powers was peaceful and ever rarely resulted in conflict, the Dutch High-Commissioner of New Amsterdam Adrianus Bakker called the relationship "Cold but rather acceptable".
A contentious issue was the Ohio river basin which was claimed by both New Holland and New France. These tensions had resulted in a skirmish in July 1751 where 27 Dutch soldiers were killed, tensions once more erupted when a French officer was killed by a group of Dutch troops while on expedition at the river's fork.
The British colonies to the North were very friendly with their Southern neighbor, though the Dutch had declared themselves a neutral power in the event of war it enjoyed a close trade relationship with Great Britain. In September 1751 Dutch troops arrived to supplement the 3,000 Militia that was gathering in near Fort Frisia.
