Benjamin Marie Petit (April 8, 1811 – February 10, 1839) was a Catholic missionary to the Potawatomi at Twin Lakes, Indiana, where he served from November 1837 to September 1838.
A Potawatomi Trail of Death marker in honor of Father Petit at St. Philippine Duchesne Park in Linn County, Kansas, was dedicated on September 28, 2003.
His experiences and observations of his missionary work among the Potawatomi and their march to Kansas survive in the numerous letters he wrote to family, friends, and colleagues.
After practicing law for three years, he left the profession to enter the Seminary of Saint Sulpice in Paris, France, to begin studies for the priesthood.
[11] Within a few months of his arrival, Father Petit had resigned himself to the Potawatomi's impending removal to reservation lands set aside for them west of the Mississippi River.
[12] In July 1838 he reported to Bishop Bruté that the Potawatomi's efforts to resist removal from Indiana had failed, and declared "the land is lost, and without recourse, I believe.
As he explained in a letter dated September 14, 1838, to his family, "It is sad, I assure you, for a missionary to see a young and vigorous work expire in his arms.
[16] Father Petit was willing to join his Potawatomi parishioners on their journey, "at least until I can place them in the hands of another pastor,"[17] but Bishop Bruté initially declined his permission.
On September 7, three days after the Potawatomi's departure from Twin Lakes, Father Petit formally accepted General Tipton's invitation to join the caravan.
[19] Father Petit described his arrival at the encampment on Sunday, September 16: "I came in sight of my Christians, under a burning noonday sun, amidst clouds of dust, marching in a line, surrounded by soldiers who were hurrying their steps.... Nearly all the children, weakened by the heat, had fallen into a state of complete languor and depression.
"[20] Tipton commented in a letter dated September 18, 1838, that Father Petit "has, both by example and precept, produced a very favorable change in the morals and industry of the Indians; that his untiring zeal in the cause of civilization has been, and will continue to be, eventually beneficial to those unfortunate Pottawatomies when they reach their new abode.
[22][23] During the journey Father Petit conducted mass, blessed the graves of the dead, and baptized the dying children, including newborns.
[19][25] He later reported that the conditions began to improve when the caravan arrived in Missouri, especially after the Potawatomi were allowed to hunt for wild game to supplement their diet.
[26] Upon arrival at their reservation lands along the Osage River on November 4, 1838, the Potawatomi were placed under the supervision of the local Indian agent, and Father Petit completed arrangements to transfer his charge to Christian Hoecken, a Jesuit missionary who had worked on the Kickapoo mission.
[6] Father Petit, who was severely weakened from the journey, continued to suffer from a serious illness, including fever and exhaustion, and stayed in the area for six weeks to recuperate.
Still too weak to ride a horse, Father Petit traveled east in an open wagon in the rain and over bad roads to reach the Jesuit seminary on January 15, 1839.
