The sappers spent almost four days uncovering the bomb which was found to contain a very damaged delayed-action fuse mechanism which could not be removed in situ.

Second Lieutenant Campbell was called upon to deal with an unexploded bomb in the Triumph Engineering Company's works in Coventry.

This was done by lorry with Second Lieutenant Campbell lying alongside the bomb to enable him to hear if it started ticking so he could warn the driver to escape.

Unfortunately, he was killed the next day whilst dealing with another unexploded bomb.His George Cross is on display in the Royal Engineers Museum.
