A low-level aerial photograph taken in 1948 shows two anti-tank blocks, one probably 3' square and the other 3' wide x around 8' long, across the track between the pillbox at TM 0234 2337 (SMR 10882/MCC5051) and the R. Colne. The smaller block is alongside the pillbox and the larger one fills the remaining gap to the edge of the river bank. The shadow cast by the 8' long block suggests that it tapered down to the ground at its river bank end.<1>

This location is almost certainly where the defensive line around the S side of Colchester joined the River Colne Eastern Command Line and thus these blocks formed the last element in this southern defence.
