The Liberator, May 15, 1863, pg 2 has an account of the meeting at Tremont Temple, with Thomas Sims. Sims had been returned to slavery from Boston in 1851, and was now back again, free. About a thousand people gathered to hear his account of these last twelve years in slavery. He had been put in prison, where he had a severe sickness, which may account for the fact that he was not whipped during that time. As soon as his condition allowed he was sold. Spent most of his time in Vicksburg, married, and has a child, now seven or eight years old. Three slave friends joined in planning his escape, in a dug-out boat. They passed through a rebel battery under cover of clouds, reached the pickets of General Grant in safety. Grant gave them a paper certifying and authorizing passage to the North.
