[William Clayton Writings] [Clayton has a long account of Porter Rockwell's shooting of Frank Worrell of the mob who was chasing J.B. Backenstos. Backenstos told Porter to shoot: Porter told B. not to be scared for they had fifty two with them meaning fifty two shots.]
.. A committee of five viz. Peter Haws, Andrew H. Perkins, Erastus H. Derby, David D. Yearsley and Solomon Hancock were appointed to carry a letter Col. Levi Williams stating to him that if the mob would cease their destructive operations, it is our calculations to leave the country in the spring, and requesting Williams to return a written answer, whether they would desist or not. The letter was signed by Prest. Young & others. About 7 o clock Backenstos with an escort of from fifty to one hundred men started for Carthage to fetch B's family and Demings family to Nauvoo.
