During the night of 9 June 1772, French sentries at the hospital camp noticed about six Māori prowling. In the morning it was discovered that Māori had also been prowling around a second camp where the French had been making masts. The next day Māori arrived with a present of fish. Roux said the Māori were astonished at the blunderbusses he had mounted outside his tent. He noticed the visiting chief taking a close look at the weapons and how they worked, as well as the defences of the camp, and became suspicious of his motives. The chief asked for the guns to be demonstrated and Roux shot a dog.
