Tredegar Battalion. – This fine body of soldiers, composed, as our readers are aware, of the workmen of the Tredegar Foundry, made a fine display of their parade on Saturday evening. One of these companies was equipped with twelve-pounder howitzers. Over 200 appeared in the parade above spoken of, and were in charge of Major Archer, who had been at such trouble to acquaint his men with the details of company and [illegible] drill.
