These proposals being accepted, the commissioners waved their hats as a sign that the treaty was concluded.
At that instant three shots were fired from the ramparts, and cries of "Treachery! treachery!" were heard on every side.

The Catholic chiefs returned to the tower, while the Protestants, believing that the commissioners were being assassinated, reopened the cannonade; but finding that it took too long to complete the breach, ladders were brought, the walls scaled, and the towers carried by assault.

Some of the Catholics were killed, the others gained Froment's house, where, encouraged by him, they tried to organise a resistance; but the assailants, despite the oncoming darkness, attacked the place with such fury that doors and windows were shattered in an instant.

Froment and his brother Pierre tried to escape by a narrow staircase which led to the roof, but before they reached it Pierre was wounded in the hip and fell; but Froment reached the roof, and sprang upon an adjacent housetop, and climbing from roof to roof, reached the college, and getting into it by a garret window, took refuge in a large room which was always unoccupied at night, being used during the day as a study.
Froment remained hidden there until eleven o'clock.

It being then completely dark, he got out of the window, crossed the city, gained the open country, and walking all night, concealed himself during the day in the house of a Catholic.
