This coast artillery battery, situated north of Portkil Point and east of Kilcreggan, was one of five used during the First World War to defend the important port and ship-building centre on the Clyde. This was a powerful battery of two 6-inch naval guns (NS28SE 39.01), capable of tackling a large enemy warship coming up the river, and two 4.7-inch Quick Fire guns (NS28SE 39.02) (intended to tackle faster, smaller vesssels). This battery was paired with another, at Fort Matilda, on the south side of the estuary (NS27NE 96). The estuary is about 2.2km wide here, but the larger guns had a range of almost 11km, firing an armour-piercing shell weighing 45kg.

The battery was built between November 1900 and 31 March 1904, by Aikenhead Builders, Greenock. The estimated cost of the battery was £21,856 and there is a note on a February 1908 War Department record drawing of what was built, that no final price could be stated because, at the time the drawing was done, there was a dispute with the contractor. The price for a smaller and less complex battery further down the river, by the same contractor, was £16,000 - around £1M today.

The battery originally comprised the pair of 4.7-inch emplacements at the east end, and the pair of 6-inch emplacements about 180m away to the west. At a point mid-way between them were a cookhouse, toilets and a store (NS28SE 39.08). In both pairs of emplacements the gun pits lay above a magazine building, deeply buried in the ground on the side exposed to an enemy.

Towards the end of 1908 plans were in hand to build a new combined battery control post and Electric Light Director control post, just above and behind the 6-inch guns (NS28SE 39.03). This two-storey building was deeply buried on the side exposed to the enemy, with only its observation windows exposed above ground. Further buildings, offices for the Royal Artillery staff and the resident Royal Engineers, stores and quarters for a caretaker, were all being designed at the same time. A later map shows that battery control/ELD post and the offices etc had been built before 1915, a fire control post to the E and slightly behind the BC/DEL post, of which drawings dated 1913 exist, was built.

Two Defence Electic Lights - powerful searchlights to illuminate targets at night - were placed closer to the shore than the guns (NS28SE 39.05).

Record maps drawn in 1916 show that a large accommodation camp (NS28SE 39.07), comprising 10 large barrack huts and accompanying stores, cookhouse etc had been built to the east of the battery, protected by the lie of the land from enemy fire.

Maps drawn in 1916 also show the strong defences of the battery itself, to protect it from an enemy attack by land. Defensive trenches were dug on the tip of Portkil Point and the whole landward side of the battery was surrounded by a barbed wire entanglement and six of what were called ‘blockhouses’ (structures that would later be called pillboxes). An outer line of defences was constructed between 700m and 1.6km from the battery, comprising five ‘positions’, each of which had one, three, or most commonly two, blockhouses, and trenches: there were 12 pillboxes in total in the outer defensive line. Other shelters, latrines and officers’ huts were built around. The HQ of the defensive troops was at Portkil farm. At least one of the pillboxes survives (NS28SE 39.06).

The 6-inch guns were removed in 1916 and installed further down the river at the Cloch Point battery (NS27NW 21). The two 4.7-inch guns were removed in 1928. The battery was not re-commissioned in the Second World War but the area was used as a naval base.

The area of the battery is now used for housing but many elements of the battery survive and some buildings have been restored, for example as holiday accommodation. Lengths of the original fence survive beside Fort Road,
