"It is now some time since your gallant son, Sergeant M. H.

I am glad to tell you that the King has awarded the Military Medal for valour to your son for what he did in repelling a German attack on May 23rd, 1916, and for his skill and courage on that occasion. The award is late in coming, but I trust will reach you safely, and that you will accept the deep and sympathetic congratulations of the whole Battalion on your son's gallantry. We share with you in your sorrow, and also your pride.
Believe me, yours sincerely,
