Help requested, 1 RIF battle honour "ST OMER-LA BASSEE' notification

[John Mulcahy]

Is anyone on the site knowledgeable on where I might find a copy of the notification of the award of battle honours?

In particular the award of the honour "ST OMER-LA BASSEE" to The 1st Battalion, The Royal Irish Fusiliers.

This Battle Honour was awarded for actions during the period 23-29 May 1940 in the battalion's defence of the southernmost edge of the Dunkirk perimeter.

I have done a quick search of the NA archives, The Gazette and Hansard but have found nothing.

thanks in advance for any help.

John
