Your impression about Bastogne was correct according to this brief paragraph from the 90th. Infantry Division's Combat Narrative.
" The division attacked 9Jan45 and cut the Bastogne-Wiltz Road at Doncels on 11Jan45 It captured Bras 13Jan45, and fought the Battle of Oberwampach 16-18Jan45. "
Prior to that action,"the 358th and 359th Infantry Regiments assaulted across the Moselle River at Malling and Cattenom on 9Nov44. ... The 359th. IR reached the Nied River at Conde'Northern 18Nov44. The division attacked toward the Saare River 25Nov44, which it reached 29Nov44, and cleared south of Merzig. On 6Dec44 the division assaulted across the Saare between Rehlingen and Wallerfangen against heavy opposition.
The Battle for Dillingen Bridgehead and West Wall Fortifications was fought 6-18Dec44, when the division withdrew from the bridgehead 19Dec44, and regrouped back on the west bank of the Saare by 22Dec44."
Perhaps this information will provide the family with more insight into Geo. Thos. Snowden's plight in the area of his death 10Jan45.
My reference : " WORLD WAR II ORDER OF BATTLE", by Shelby L. Stanton, published by Galahad Books, NYNY.
I have another reference which I will review for any other information, if available.
Please note that I am aware of your inquiry re: Louis Geo. Caron, and I will look up his unit history in the morning.
