It will be remembered that early in the War a Capt. Von Weghorn, an officer of the Prussian Army, startled the civilized world by an attempt to destroy the International railway bridge spanning the St. Lacroix River, between McAdam Junction, on the Canadian side, and Vanceboro, on the United States’ side. A suitcase filled with dynamite was placed between the piers of the northeast corner of the bridge on the Canadian side. The attempt failed, the bridge being only slightly damaged and traffic not delayed. It was considered expedient, however, to place an armed guard on this bridge on the Canadian side. To Lieut.-Col. E. C. Dean, A.D. of S. & T., M.D. No. 6, fell the duty of making the necessary supply and other arrangements for this guard. A similar guard was placed over the new railway bridge spanning the St. John River at St. Leonards. Guards were also established over the Marconi Wireless Towers at Newcastle, N.B., and Barrington Passage, the latter under command of Lieut.-Col. T. M. Seeley. These guards required the usual attention on the part of the Army Service Corps. To maintain the guard at Barrington Passage was a cause of anxiety, as it was stationed at a point some miles off the main road, in the midst of a wilderness, and could be reached only in good weather, as the road leading to the Wireless Station from the main highway was-well, simply impossible. Permanent guards were also maintained at Louisburg, Glace Bay, Whitney Pier, Sydney, North Sydney, Sydney Mines, Cranberry Head, Chapel Hill, Canso and various other places.
