[Joseph] discharged one barrel of a six-shooter (pistol) at random in the entry, from whence a ball gazed Hyrum's breast, and, entering his throat, passed into his head, while other muskets were aimed at him, and some balls hit him. Joseph continued snapping his revolver round the casing of the door into the space as before--three barrels of which missed fire--while Mr. Taylor, with a walking stick, stood by his side, and knocked down the bayonets and muskets which were constantly discharging through the doorway, while I stood by him, ready to lend any assistance, with another stick, but could not come within striking distance without going directly before the muzzle of the guns. When the revolver failed, we had no more fire-arms, and, expecting an immediate rush of the mob, and the doorway full of muskets--half way in the room, and no hope but instant death from within--Mr. Taylor rushed to the window, which is some fifteen or twenty feet from the ground.
