Mobilisation The TA was expanded in the years of tension leading up to
World War II, and a new 152 Heavy Battery was formed in October 1937. In 1938, the TA replaced its traditional unit designation of 'brigade' with 'regiment', and the unit was redesignated the
Tynemouth Heavy Regiment on 1 October. On the outbreak of war, on 3 September, the regiment was responsible for manning one 9.2-inch and four 6-inch guns. The invasion threat after the
Dunkirk evacuation and
Fall of France led to a massive increase in Britain's coast defences. In addition to the existing fixed defences, a number of Coast Defence Emergency Batteries were established in May and June 1940, including: •
Seaham (Sunderland) – 2 × 6-inch Mk VII •
Whitburn (Sunderland) – 2 × 6-inch Mk VII • Park (
South Shields) – 2 ×
6-inch Mk XII • Gloucester (Blyth) – 2 × 6-inch Mk XII • Frenchman's (South Shields) – 2 × 6-inch MkXII Park, Gloucester and Frenchman's batteries were initially established by the
Royal Navy and transferred to the RA when sufficient coastal gunners had been trained.
Coast Regiments The expansion of the RA's coast defence branch led to the Tynemouth Heavy Regiment being split into three coast regiments on 14 July 1940:
508 (Tynemouth) Coast Regiment Formed with A, B and C Batteries. On 31 December, it was joined by 348 Coast Bty from 554th Coast Rgt at
Poole,
Dorset. On 1 April 1941, A Bty was split up and the regiment was reorganised as: • Regimental HQ (RHQ) at Tynemouth Castle in Tynemouth Fire Command • 259 Coast Bty from A/508 – 9.2-inch guns at Tynemouth Castle • 260 Coast Bty from A/508 – 6-inch guns at Tynemouth Castle • 261 Coast Bty from A/508 –
4-inch guns at Tynemouth Castle • 262 Coast Bty from B/508 – at Spanish Battery • 263 Coast Bty from C/208 – at
Clifford's Fort, North Shields • 348 Coast Bty – at Frenchman's Battery, South Shields • 420 Independent Coast Bty joined 10 November 1941 from
Needles Battery,
Isle of Wight 509 (Tynemouth) Coast Regiment Formed with A and B Batteries. On 31 December, it was joined by 312 and 314 Coast Btys. On 1 April 1941, A and B Btys were numbered: • RHQ at Sunderland in Sunderland Fire Command • 264 Coast Bty from A/509 – Roker • 265 Coast Bty from B/509 – Barrows • 312 Coast Bty – Whitburn • 314 Coast Bty – Seaham • 397 Coast Bty – joined from 511th (Durham) Coast Rgt 30 June 1942
510 (Tynemouth) Coast Regiment Formed with A Bty, joined by 311 (formed at Gloucester Battery) and 313 Coast Btys on 31 December 1940: • RHQ at Blyth • 266 Coast Bty from A/510 – Blyth • 311 Coast Bty –
Druridge Bay • 313 Coast Bty – Tynemouth Castle • 68 and 70 Coast Observer Detachments (CODs) – joined August 1941 • 310 Coast Bty – joined from
505th (Forth) Coast Rgt 3 November 1941–
Spittal • 19 COD – joined January 1942, replaced by 97 COD by end of year • 20 and 22 Mobile Defence Troops – attached to 311 Coast Bty January 1942 • 80 COD – joined April 1942 • 322 Coast Bty – joined from 565th Coast Rgt at
Hunstanton,
Norfolk, 15 May 1942
Mid-war At their height, in September 1941, the Tyne defences contained the following guns: • Blyth • 4 × 6-inch • Tyne • 1 × 9.2-inch • 6 × 6-inch • 1 × 4-inch • 2 ×
12-pounders • South Shields • 2 × 6-inch • Sunderland • 4 × 6-inch • 2 × 12-pounders • Seaham • 2 × 6-inch All three regiments came under the command of
IX Corps HQ by May 1942. By then, the threat from German attack had diminished and there was demand for trained gunners for the fighting fronts. A process of reducing the manpower in the coast defences began. 265/509 Coast Bty was placed in suspended animation on 20 June, just before 397 Bty arrived, and 261/508 Coast Bty was disbanded 10–17 October. 322/510 Coast Bty went to War Office Control on 7 May 1943, but was replaced by 444 Coast Bty, newly formed at Gloucester Battery. 420/508 Coast Bty was disbanded on 20 September 1943. 509th Coast Rgt was placed in suspended animation on 1 April 1944 and its remaining batteries (264, 312, 314, 397) were regimented with 508th Coast Rgt. 70 Coast Observer Detachment was also disbanded in April 1944.
Late war As the campaign in North West Europe progressed after
D Day, the manpower demands of
21st Army Group led to further reductions in coastal artillery. By this stage of the war, many of the coast battery positions were manned by
Home Guard detachments or in the hands of care and maintenance parties.
616 (Tynemouth) Regiment Then, in January 1945, the War Office began to reorganise surplus anti-aircraft and coastal artillery regiments in the UK into infantry battalions, primarily for line of communication and occupation duties in North West Europe, thereby releasing trained infantry for frontline service. On 15 January 1945, all the remaining Tyne batteries were transferred to the command of
526th (Durham) Coast Rgt, while RHQ 508th Coast Rgt and Tynemouth Fire Control HQ were converted into
616 (Tynemouth) Regiment, RA. After infantry training in Scotland with
301st Infantry Brigade, the brigade transferred to 21st Army Group on 9 May 1945, and landed on the
Continent on 15 May (a week after
VE Day), where it came under the command of
First Canadian Army. The regiment was placed in suspended animation on 31 October 1945, completing the process on 24 November. ==Postwar==
