On 24 April 1916, a force of German battlecruisers and cruiser set out from Kiel to bombard the coastal towns of Lowestoft and Yarmouth. Later that day, the German battlecruiser struck a mine, and the resultant radio traffic warned the British of the German operation. The Harwich Force, including "Lightfoot", set out to counter them on the night of 24/25 April. On the morning of 25 April the German raiding force was sighted. Heavily outnumbered, Tyrwhitt turned away in an attempt to lure the German forces away from Lowestoft, but the Germans ignored this move and shelled Lowestoft before moving North towards their next target, Yarmouth. On observing this Tyrwhitt again turned his ships in pursuit of the raiders, and engaged the light cruisers screening the German force just as the German battlecruisers started to shell Yarmouth. The German battlecruisers aborted their bombardment to engage the Harwich force, hitting the cruiser and the destroyer but retired to the East rather than attempt to destroy the smaller British force. "Lightfoot" was undamaged.
