In accordance with orders received on December 16, 1916, Lieut. Crosby and fifty other ranks were warned to hold themselves in readiness to proceed Overseas. They embarked on the _S.S. Scandinavian_ on January 23, 1917. Recruiting continued steadily and on March 26, 1917, Capt. W. H. L. Doane with fifty other ranks proceeded Overseas on the _S.S. Missinabie_. Capt. F. H. Palmer being now the senior Lieutenant of the Battery was promoted to Captain, March 27, 1917. On April 12, 1917, Lieut. M. B. Archibald, 1st R.C.S., and Lieut. R. D. Lacon, 1st R.C.A., were appointed to the Battery. Lieut. R. P. Freeman and fifty other ranks were warned on May 17, 1917, to hold themselves in readiness to proceed Overseas. They sailed on the _Olympic_ on the 28th of May. On November 5, 1917, warning was received that three officers and two hundred N.C.O.’s and men would proceed Overseas. As the Military Service Act was now about to become law, organizations which had previously handled voluntary recruiting would now completely change their character. Ample man power being available, it would only be necessary to outfit and start preliminary training of men raised under the Act. In view of this the Draft embarked for Overseas service on November 23, 1917, on the _S.S. Metagama_, consisting of Major J. M. Slayter, Captain Palmer and one hundred and fifty N.C.O.’s and men. Lieutenant Archibald and fifty other ranks proceeded Overseas on the _S.S. Olympic_. Lieutenant Lacon, and some forty men, the latest joined recruits, were left in Halifax to carry on the Depot under the Military Service Act. As the personnel of the detachment who made up this sailing were of an exceptionally high character, and had had considerable training in specialties, it was hoped that they might be retained as a Battery for service Overseas. On arrival at Witley, Surrey, England, it was found that there were such heavy demands for reinforcements for Batteries and Brigades already authorized, that it would be impossible to retain the organization as it landed at Witley. Specialists were sent for extra courses, and as these were completed were drafted very largely to the newly-formed 10th, 11th and 12th Siege Batteries, and to the 3rd Brigade of the C.G.A. The Depot of the 10th Siege Battery at Halifax continued under Major George Oland, with Lieutenant Lacon, Lieutenant McNair and Lieutenant Baird, sending forward drafts and having raised and equipped and sent forward some ten officers and about eight hundred N.C.O.’s and men. The Depot at Halifax was finally absorbed after the Armistice in the 6th Artillery Depot. These are the bare facts as taken from records, which do not signalize the splendid self-sacrificing work of such officers as Captains W. H. L. Doane, R. P. Freeman, F. H. Palmer, and R. E. Jamieson; and such N.C.O.’s as Jenkins, Fultz and Holmes.
