Although many messages were sent by agents, the Twenty Committee considered that Ironside was quite unrealistic and as a result was cautious about promoting it too heavily. Most of the information was sent with words of caution or uncertainty to ensure that the agent would not be compromised. One of the most critical Bodyguard agents, Garbo, did become involved on 5 June, but only in forwarding the message of a fictional sub-agent who he had already identified as unreliable (MI5 hoped that this would cover for, in their opinion, the implausible nature of the story). The agent's report explained that a US division based in Liverpool was preparing to head to Bordeaux.
