Captain (Temp/Major) J.M. Calvert D.S.O.

OPERATIONS IN BURMA - MARCH 1943

Under the leadership of Major CALVERT, No. 3 Column carried out a series of highly successful attacks on the SHWEBO-MYITKYINA Railway on 6th March 1943. In the course of these attacks the railway line was blown in 75 separate places, a number bridges were destroyed and quantities of mines sown. The operation was not carried out without interference from the enemy and Major CALVERT was interrupted in his work of destruction by a strong force of enemy from NANKAN Station. This force he engaged with determination, compelling it to withdraw leaving fourteen dead on the field. He then returned and completed the destruction of the railway.

Throughout this operation and the approach march to the railway, Major Calvert was isolated from all assistance; the surprise he achieved and, in particular, the great thoroughness and skill with which the operation was carried out were due to his personal qualities of leadership and supervision. The destruction of the railway was carried out after a march through enemy occupied territory of over 200 miles, occupying sixteen days. Had the column not been handled with great skill, and faithful observance of the principles of long range penetration taught, it would never have reached the railway unopposed.
