After perusing the documents on Darrel Pace`s website for the 1142EC Group, i found the 251st ECB was attached to the 1142nd on 1 Nov 1944 at Sichen, Belgium.
On 7 Nov 44 the 251st was relieved of attachment to 1142D Engr C Grp by attachment to XIII Corps. Auth: Troop assignment 52 HQ, 9th US Army, dtd 6 Nov 44.
XIII Corps was under 9th US Army, 21st Army Group during that period. I have not yet found out if the 251st was still in XIII Corps in February `45 at the time of Mr Rose`s death on 23 Feb.
23 Feb, 45 was the start of "Operation Grenade", 9th Army`s attack across the Roer River.
There is also a copy of the unit history at the Eisenhower Library.
