British ships both failed to report engagements with the enemy but also, in the case of cruisers and destroyers, failed to actively seek out the enemy. A culture had arisen within the fleet of not acting without orders, which could prove fatal when any circumstances prevented orders being sent or received. Commanders failed to engage the enemy because they believed other, more senior officers must also be aware of the enemy nearby, and would have given orders to act if this was expected. Wireless, the most direct way to pass messages across the fleet (although it was being jammed by German ships), was avoided either for perceived reasons of not giving away the presence of ships or for fear of cluttering up the airwaves with unnecessary reports.
