Naval Fire Support of the WWI Western Front: Long Patrol, Part 2, Abercrombie Class

The Abercrombie class combines shallow draft, heavy armor, slow machinery, and a twin 14-inch turret in a monitor designed around coastal bombardment.

Four Bethlehem Steel turrets stranded by the British blockade became the armament for purpose-built monitors instead of the Greek battleship Salamis.

The Army needed heavier fire closer to shore than deep-draft pre-dreadnoughts could provide, so the monitor hull was designed around the available 14-inch turrets.

A centered arrangement balances turret and machinery weight, but only 2,310 indicated horsepower moves the broad monitor at low speed.

Plans to name the four monitors for Grant, Lee, Farragut, and Jackson were abandoned while the United States still claimed neutrality.

Profits and shipping from the Atlantic slave trade helped sustain British naval power before the Royal Navy later took part in suppressing the trade.

Abercrombie and Havelock fit together in a Belfast building dock, while their heavy turrets required fitting on the Clyde.

Commissioned in May 1915, Abercrombie spent the war supporting operations around the Dardanelles, Aegean, and Palestine.

Havelock left the Dardanelles in 1916 to guard Lowestoft, then followed an obscure path through disarmament, reserve use, and repeated sale.

The unfinished Salamis evolved into a plan for a fast, heavily armed battleship while Greek and Ottoman planners watched dreadnoughts offered across the international market.

Britain could improvise new monitor hulls around imported turrets because decades of naval and merchant investment had created spare yards and fitting capacity.

Raglan bombarded Ottoman positions and supported the Third Battle of Gaza before a sortie found the monitor force without its battleship cover.

Yavuz Sultan Selim and Midilli overmatched Raglan and M28 at Imbros after the slow support ships were left without a capable covering force.

British submarines could not exploit Yavuz's mine damage: E12 was unavailable, while E14 failed to find the battlecruiser and was lost during its return.

Roberts moved from Eastern Mediterranean service to coastal defense, then survived for trials involving an airship-base proposal and underwater protection.
