Hi Mike;
The unit that would have transported the SD&G across the Rhine, would have been 1 Northants Yeomanry (33rd Armd Bde), they were the 'Buffalo' equipped unit in support of the 154th (H) Inf Bde of the 51st (H) Div, 9th Cdn Inf Bde having crossed to both reinforce the 154th Bde bridgehead and to relieve them.
4 RTR were in support of the 153rd (H) Inf Bde.
Cheers
