What the MI5 Files Record: Equipment of the 1940–41 Agents

The wartime spy case files contain no consolidated inventory of equipment; each agent’s gear must be reconstructed from scattered documentation. Any attempt to identify patterns requires scanning hundreds of documents across dozens of individual files. Years ago, I began compiling a spreadsheet to track key information on the wartime spies, specifically those tried under the Treachery Act.

In attempting to determine the provenance of certain items now held by the Imperial War Museum, I have extracted a subset of data from that spreadsheet relating to the equipment under examination: parachute gear, head protection, flying suits, pistols, knives, and wireless sets.

The documentation is uneven. Local police were often the first to detain an agent and inventory his possessions, and their thoroughness varied. The London Colney police, for example, recorded that Karel Richter carried a Browning pistol and noted its serial number. The Edinburgh police, by contrast, recorded that Werner Walti carried a Mauser pistol but did not record its serial number. In other instances, particularly in the files of double agents such as Wulf Schmidt and Gösta Caroli, material has been weeded over the decades. We may learn that an agent carried a “pistol,” yet must infer the presence of a knife from references to cutting up a parachute.

What follows is therefore a working reference point. Some files contain exceptionally detailed descriptions — particularly of parachute equipment — which will prove useful when examining the surviving artifacts. Nikolay Steen Marinus Hansen has been included, although not tried under the Treachery Act, because he arrived by parachute and his equipment is a potential candidate for comparison with the IWM parachute gear.

Table summarizing key equipment recorded in the case files of agents who arrived by seaplane, small boat, or parachute between 1940 and 1943.
Agents who entered Britain posing as refugees, and who carried no wireless equipment, have been omitted.

Columns 4, 5, 6: A triple en dash (– – –) indicates that the item is not applicable to that method of arrival (e.g., no parachute gear for agents arriving by boat).
Column 9: “S” denotes Sender (transmitter) and “E” denotes Empfänger (receiver), as recorded in the German documentation.
Column 10: “T” denotes transmitter and “R” denotes receiver. Some agents arrived carrying only a transmitter.

This table does not attempt to interpret the equipment, only to record what the surviving files document. In the posts that follow, we will examine individual categories of gear in greater detail and compare the recorded inventories with the surviving artifacts.
