647 Coy ASC (10 Pontoon Park)

647 Coy was formed on 23 February 1916 at Catford, London under command on Capt FP Landon and designated 10 Bridging Train MT.

 The Establishment was 28 FWD 3-ton lorries, 4 Vauxhall cars, 7 motorcycles, 2 workshops and 2 store lorries, 3 officers and 148 other ranks.

The time at Catford was spent training drivers and delivering supplies to various London depots. On 28 March the company moved to Grove Park where basic training continued before moving to Witley Camp on 23 April. Here a Royal Engineer Sapper Detachment joined and pontoons were drawn from Aldershot.

After training with pontoons, the company departed for Avonmouth on 4 August and arrived at Rouen on the 14th.

A few days at Rouen Rest Camp were followed by a move to Saint-Hillaire-Cottes.

Here the Unit was employed on local building projects and converting old-type Trench Mortar Bombs to up-to-date versions.

On 1 November the company joined I Corps at Ruitz.

January 1917 was spent using 4 pontoons to assist the town of Bruay which was engulfed by serious flooding.

The Unit was then employed assisting the construction of roads and railways in the XIII and Canadian Corps Areas.

On 27 January Capt Landon handed over command to Capt TS Jackson.

In June, the pontoons with superstructures were handed over to 2 Pontoon Park and 10 Pontoon Park took over maintenance of 9 pontoon bridges on the River Lys between Houplines and Bac-Saint-Maur. The rest of the year was spent on extraneous duties and construction of huts.

The beginning of 1918 was spent providing a considerable amount of gun traction until March. From then the company was employed transporting pontoons and bridging equipment for Royal Engineer Field Companies.

From the start of the German Spring Offensive in April the work involved destroying bridges after allied troops had passed over.

The Unit was then fully occupied transporting barbed wire, pickets and hurdles and constructing GHQ defence lines and lorry standings.

From the end of August the lorries were fully employed carrying heavy bridging equipment and building bridges in front of the British advance.

This was often conducted under heavy German shellfire.

By 31 August they had advanced to Wailly where they came under the orders of the First Army Officer i/c Heavy Bridging.

During September over 30 pontoons were delivered to the CRE 11 Division.

During October the lorries advanced with the Canadian Infantry building pontoons under the cover of machine gun fire.

This action resulted in a letter from Canadian Corps that particularly praised the efforts building bridges on 27 September at Marquion when the area was subject to very heavy shellfire.

There is no record after 31 January 1919.
