On 17th January, 1/5th Queens attacked Susteren from the west in thick mud and in pitch dark but once they were in the town, it was impossible to get their 6-pdr anti-tank guns across. So the German counter-attack was driven of by Bren Guns and fire from 3rd RHA. 'B' Company was cut off for a time, but eventually 'B' Squadron, 1st RTR managed to get across the Beek and come to there assistance.
At Susteren, 1st RTR lost seven tanks for Panzerfaust teams and anti-tank guns, but despite the savage battle, 11th Hussars managed to put a patrol into Oud Roosteren, which was later captured by 6th King's Own Scottish Borders, from 52nd (Lowland) Division.
