Yes I am quite aware of what the "heavy regiment" was.stg 44 wrote: The 'heavy regiment' was an artillery unit. The 6th Battalion Green Howards of the Yorkshire regiment apparently was there as well, the only infantry unit attached. I thought they were added later, but apparently they were there from the 23rd on near Gravelines on Aa Canal with the French. Apparently they were a newly raised unit of reservists.
As to the 6th Howards, here's a brief history of the battalion in the time period.
6th Battalion, The Green Howards (Alexandra, Princess of Wales’s Own Yorkshire Regiment) (T.A.)
69th Infantry Brigade – 11 September 1939 to 31 August 1945
The battalion was raised from the 4th Battalion at Middlesbrough and had its first officer commissioned on May 25th, 1939. The 6th Green Howards were initially to share the 4th Green Howards’ HQ in Middlesborough while it established itself. In June 1939, the 6th Green Howards was established and had its companies co-located with their counterparts in the 4th Battalion. ‘A’ Company at Richmond and Thirsk, ‘B’ Company at Guisborough, ‘C’ Company at Skelton and ‘D’ Company at Yarm, Northallerton and Stokesley. HQ Company would be located in Redcar and Skelton. The brigade and battalion were administered and embodied under the 50th Infantry Division from September 3rd, to October 2nd, 1939. After call-up the battalion served on guard duties at Middlesbrough, Redcar, Stockton and Hartlepool. In April 1940, it left Stockton railway station for Dover, embarking on April 24th, 1940. It landed at Calais on the 25th and moved to Irles, France to work on the RAF landing grounds. It moved to Sauchy Cauchy on May 17th, 1940 to prepare defences there. The battalion was moved to Canal du Nord and withdrew the next day to Saudimont. It was in positions on May 20th, on the River Scarpe at Roveux. After that it withdrew to Farbus and by nightfall was located at Vimy Ridge. The next day it moved to Gandecourt. The 23rd Division was now placed under the command of GHQ BEF and the battalion moved to Gravelines for defence for two days. After it withdrew to Dunkirk and to the coast there at Bray Dunes on May 29th.
