Firing at Fort Lytton
Firing practice was carried out this morning at Fort Lytton by the 11th Howitzer Battery, R.A.F.A., under the command of Captain Long, and by the 6-inch guns in the fort. The latter were manned by the 22nd Coast Battery, under the command of Lieutenant Reville.
The 111th Battery first fired a series of 12 rounds, followed by a second series of 16 rounds at a target anchored out in the bay at a range of 3,200 yards. Fort Lytton and its environs were wreathed in rain and mist, and visibility was poor. Nevertheless, excellent results were obtained.
The battery fired from a concealed position behind a hill, range taking observations and fire control being effected from the summit.
