under an officer whom I since know to be Lieutenant Avelyn. On getting to the breach I observed the prisoners using an iron bar to enlarge it. I remonstrated and told them it was the prison barrack-yard, and that it would be dangerous for them to attempt to force in; the prisoners shouted and threw stones through the breach, and still continued at times to enlarge it.

At this time I should suppose there were from 4 to 500 prisoners in the market square; I was perfectly unarmed, and went down to remonstrate with them, using all persuasions in my power to make them return to their
