Task: Question Understanding
Input (English): Passage: Danish officials appealed for help to French colonists at Martinique, located 324 miles away. Two French ships arrived from there to St. John on April 23, 1734, carrying several hundred French and Swiss troops to try to take control from the rebels. With their firepower and troops, by mid-May they had restored planters' rule of the island. The French ships returned to Martinique on June 1, leaving the local militia to track down the remaining rebels, which they did over the next three months. The slave insurrection was considered ended on August 25, 1734 when Sergeant Øttingen captured the remaining maroon rebels. The loss of life and property from the insurrection caused many St. John landowners to move to St. Croix, a nearby island bought by the Danish from the French in 1733. Four ships carried planters and their families from Charlotte Amalie in August. While they found St. Croix to be a richer land, they had to have their slaves clear jungle before being able to live there readily.
Question: What month did two french ships arrive at St. John?
