After the Fort Dearborn massacre of 1812, Robinson (who had just returned from a trip to Bailly's trading post) with Black Partridge, Waubonsie and Shabbona protected Kinzie and his family from hostile Wabash warriors.
Robinson transported (by canoe) the Kinzie family to what became Chesterton, Indiana and the protection of (or house arrest under) Topinabee.

For the then-significant sum of $100, Robinson also undertook the dangerous mission of transporting the wounded U.S. Captain Nathan Heald and his wife Rebekah Wells (daughter of former Indian Agent William Wells who died in the massacre) and Sergeant William Griffith by canoe (over two weeks) to the British fort on Mackinac Island, from where they eventually reached British-occupied Detroit, then Buffalo.
Later, in 1814, Kinzie's half brother Robert Forsyth and other Americans would capture Bailly and three other pro-British traders at the St. Joseph River post, then Kinzie and his aide Jean Baptiste Chandonnai persuaded native leaders to an American-led conference at Greenville, Ohio which led to a treaty ending hostilities in the region.

Although Fort Dearborn had been destroyed shortly after the battle, Robinson and fellow trader Ouilmette farmed there before the fort was rebuilt in 1816.
They then sold produce to the U.S. Army.
Perhaps as early as 1814, and until 1825, Robinson had a trading post and farm somewhat away from the fort at Hardscrabble near the Chicago Portage. (
After his release, Bially would establish the Joseph Bailly Homestead in what would later become the  Indiana Dunes National Lakeshore).
During this period Robinson worked for various companies, including the American Fur Company under John Crafts and later the returned John Kinzie, until 1828 when Kinzie died and the American Fur Company left the region since fur-bearing animals had vanished not long after development of the steel trap.
Late in that decade, Robinson also had a trading post at Wolf Point, and later had a tavern in Cook County.
