Franz Claasen, a loyal slave of the van Stell family, was deeded the Mary Point Estate for alerting the family to the rebellion and assisting in their escape to St. Thomas. Franz Claasen's land deed was recorded August 20, 1738, by Jacob van Stell, making Claasen the first 'Free Colored' landowner on St. John. Denmark ended the African slave trade in the Danish West Indies on January 1, 1803, but slavery continued on the islands. When the British emancipated their slaves in the British West Indies in 1838, slaves on St. John began escaping to nearby Tortola and other British islands. On May 24, 1840, eleven slaves from St. John stole a boat and escaped to Tortola during the night. The eight men , and three women  were from the Annaberg plantation and ten Leinster Bay estates. Brother Schmitz, the local Moravian missionary, was sent to Tortola by the St. John police to persuade the slaves to return. After meeting with the Tortola officials and the runaway slaves, Schmitz returned to St. John to relay the slaves' resolve to stay away because of abusive treatment by the overseers on the plantations. After planters replaced those overseers, Charles Bryan, his wife Katurah, and James Jacobs returned to work at Leinster Bay. Kitty, Paulus, David, and Adam moved to St. Thomas. Henry Law, Petrus, and Polly stayed on Tortola. John Curry relocated to Trinidad. None of the runaway slaves were punished. Slaves and free blacks petitioned the colonial government and Denmark to abolish slavery. On July 3, 1848, 114 years after the slave insurrection, enslaved Afro-Caribbeans of St. Croix held a non-violent, mass demonstration seeking abolition of slavery. The Governor-General da:Peter von Scholten declared emancipation throughout the Danish West Indies.. How many years passed between the Bristish emancipating their slaves in teh British West Indies and the slaves on St. Croix holding a mass demonstration?
