When the Hudson River Bridge Company secured articles of incorporation for the purpose of bridging the Hudson River at Albany, the city of Troy, which was opposed to the building of the bridge, engaged Mr. Beach to endeavor to prevent its construction by an appeal to the courts. A preliminary injunction was obtained enjoining the bridge company from proceeding with their work, but an attempt to have the injunction made permanent resulted in the case being carried into the Supreme Court of the United States, where the bill of complaint was dismissed.

During the administration of Governor Seymour, while the Civil War was in progress, Mr. Beach was retained to defend Col. North and others, who were charged with tampering with the votes of soldiers.

This case was carried into the Supreme Court of the United States, where, during that time of high political excitement, it occasioned widespread interest. Mr. Beach not only succeeded in procuring the accjuittal of his clients, but also laid the foundation for the proceedings which ended in the discontinuance of the sy.stem of substituting military inquisitions for authorized civil courts. His argument was listened to by Senators and Representatives and his skillful conduct of the case made him the recipient of many enthusiastic manifestations of approbation.

In 1868 he obtained the acquittal before the courts of impeachment of canal commissioner Robert C. Dorn.

During his residence in Troy he was frequently tendered the nomination to a judgeship, but declined the honor. The title of judge, however, was commonly prefixed to his name.
