As Officer commanding 57 Canadian Independent Field Squadron, Royal Canadian Engineers, Major Rochester has directed the work of his squadron so outstandingly that it has reached a high standard of achievement. The squadron was formed in Canada of volunteers from civilian life and trained by him in a period of less than six months. On arrival in Korea, Major Rochester quickly showed that he was able to assess engineer tasks and employ his squadron to the best advantage to carry them out. The construction of new roads over the most difficult terrain, the bridging of water obstacles, the operation of ferries demanded the utmost from the troops under his command. By his personal example, his tireless efforts and devotion to duty, [and] his cheerfulness under adverse weather conditions, he inspired his men to labour long hours to complete in record time any task to which they were assigned. On 26 July 1951, 57 Canadian Independent Field Squadron, Royal Canadian Engineers, became a part of 28 Field Engineer Regiment. His contribution to the engineer effort of the regiment has been an outstanding one of ability, good judgement, tirelessness and devotion to duty. A particular achievement was his organization of work for the construction of roads to a bridge site on the River Imjin at the worst of the rainy season over extremely difficult terrain which had hitherto been considered impracticable. This entailed personal supervision of his men throughout the daylight hours, often in drenching rain while his plant operators and men worked in shifts. His tremendous efforts in this task literally laid the foundations for the successful crossing of the Imjin River in the first week of September.
