In November CCXC Bde got its first rest for eight months, then it was back in the line in the Ypres Salient in December.
In January 1918 58th Division was moved to the area of Villers-Bretonneux in Fifth Army.
It was in the front line when the German Spring Offensive opened on 21 March, and over the next few days was forced back wit heavy casualties.
When XXCX Bde was forced to withdraw, it could bring away only eight of its 24 guns, half of them howitzers from D Bty.
In the 'Great Retreat' that followed the battery came into action 18 times.
The brigade was then transferred to Amiens where it supported Australian and US troops as well as 58th Division in the Battle of Villers-Bretonneux.
A sudden attack on 28 April saw D Bty's position overrun by German troop, but a counter-attack recaptured the guns.

There followed a quiet period for the brigade, then in August it was warned for a two-day 'stunt', travelling light, without the men's blankets.
This became a continuous two-month series of actions and advances during the Allied Hundred Days Offensive, from Chipilly Wood at the Battle of Amiens (8–11 August) up the Somme Valley via Vaux-sur-Somme, Malard Wood, Clery, Saulcourt, St Emilie and Govy.
Even though the infantry of 58th Division were close to exhaustion, the artillery were kept in action.
At the Battle of Bapaume (2 September), CCXC Bde fired a creeping barrage for the attack of 47th (2nd London) Division, and at the Battle of Épehy (18 September) it did the same for 18th (Eastern) Division.
At 01.00 on 8 October the brigade fired a barrage for a night attack by 1st Battalion King's Own Yorkshire Light Infantry of 49th (West Riding) Division to break through the Beaurevoir Line.

In October the brigade was transferred by train to rejoin 58th Division in the Lens area, where it fired its last shots shortly before the Armistice.

After the Armistice came into force, skilled men began to return home.
Full demobilisation got under way in March 1919 and 58th Division's artillery left for England on 4 April.
