The German forces did not attack after darkness had fallen on the night of 28th May 1940, although considerable movement was noticeable in the surrounding country, with German troops now clearly visible to the North of the town effectively cutting off escape to the Dunkirk beaches.
At Dunkirk, by now 58,000 troops had been successfully evacuated and more than 500′ little ships’ were being assembled in Sheerness to facilitate the Operation Dynamo evacuation.
Cassel Garrison contracts
Although the garrison had suffered significant casualties, an appreciable number of enemy tanks were now lying derelict in open country. The Field Ambulance HQ in the town centre had received a direct hit from a Stuka attack resulting in several casualties, some are now buried in the towns’ cemetery.
The outlying ‘picket’ villages of Bavinchove and Zuytpeene had by now been captured by the Germans, with some survivors successfully making their way back to Cassel.

140th Regiment re-positioned in Cassel
A machine-gun platoon had reinforced the junction with the 4th Ox. and Bucks, and a section of 140 Regiment’s 18-pounders were positioned in the Ox & Bucks Battalion “keep” area in the town centre.
2nd Lieut. Gerry French, of the Intelligence Corps was killed by a mortar bomb, while on a mission to liaise with one of the field guns regarding the targeting of a German mortar position.

Later on the morning of Wednesday 29th May, another heavy and sustained attack broke out again, preceded by concentrated mortar bombardment. There were attacks from three sides simultaneously. In places the defences were driven in and casualties mounted.
During the fighting of the morning of 29th May at about 10.30, and despite his better judgement, Major Christopherson was ordered by Somerset to fire on German mortar positions. He carried out this order with one gun, positioned on the D218 Road on the Northern perimeter of Cassel and firing over open sights, but the predicted retaliation from German mortars killed two men and Christopherson himself was injured.
Christopherson’s injury meant he took no further part in the battle and the war diary, written retrospectively after his return from captivity in 1945, concludes on this day.

In spite of mounting casualties and ever-diminishing effective manpower, the German forces still did not manage to gain a foothold in Cassel. By midday the attacks slackened off and, in the afternoon, a 48th Division Royal Signals dispatch rider managed to reach the town, 24 hours later than planned, with the order from Lord Gort’s Headquarters that the garrison should withdraw and try and make a rendezvous near Dunkirk.
The fighting died down about 17.00 hrs. and it appeared that the enemy had withdrawn from their respective fronts. More German troop movement could certainly be seen away to the north, but too far away to engage with fire. By now, Cassel had been severely damaged, but, apart from occasional low-flying Luftwaffe aircraft, all action had ceased.
Planning the breakout
Brigadier Somerset started to plan the breakout. He could see that the situation at Cassel had become untenable and that there was no prospect of British counter-attack or rescue. He told his HQ staff to keep the news secret from the men as he could see that there was no realistic prospect of escape until nightfall. Somerset identified the D137 road that headed North East towards Winnezeele and sent a detachment of the East Yorkshire Yeomanry to investigate the route. The East Yorkshire Yeomanry were also assigned the task of protecting the rear of the breakout, thus assigning the men of that Regiment to almost certain capture.
Caught in a pincer
Once the news of the evacuation began to filter through, the British troops had high hopes of being able to make a successful getaway. This was to be a fighting retreat and the soldiers were armed with rifles, Bren guns and grenades. What was not known then, however, was that this withdrawal to Dunkirk was intended twenty-four hours earlier; the delayed arrival of the message now rendered withdrawal to the coast virtually impossible, as Cassel was completely surrounded and all approaches to the sea were effectively blocked by the closure of the German pincer movement around the Belgian town of Poperinghe.
Meanwhile, to the North of Cassel, the garrison of 14 men of the Gloucester Regiment under the command of Lt Cresswell at the le Peckel blockhouse, were out of contact with Somerset and were to hold out for three days of continuous German attack, only surrendering when German infantry had overrun the blockhouse and all sounds of the battle to the south in Cassel had ceased.
War Diary (Final Entry) 29th May 1940
‘An enemy attack was repulsed to the west of CASSEL by the Infantry without the gunners being called upon for assistance. I was at 145 Brigade H.Q. and was informed that a Signal Sargent from 48th Division Signals had arrived telling the Brigadier that the CASSEL garrison was to retire at once to BERGUES and that this message should have reached him during the night 28th/29th May.
The Brigadier [Somerset] decided that owing to the enemy having nearly surrounded his force he would not make the attempt until darkness. About 10.30 hrs. the Brigadier asked me to harass the enemy mortars to the N.W. of CASSEL as they were giving the Infantry an unpleasant time. I pointed out to the Brigadier that although I was quite prepared to help, any firing done by the Regiment would bring down unpleasant consequences to his immediate surroundings but he pointed out that it would be a good thing to raise the tails of the Infantry a bit higher. I therefore took one gun with its detachment and fired on the mortars over open sights. Just as the gun had got the range other enemy mortars got the range of the gun and began plastering us. The result was that two of the detachment were killed and I was knocked unconscious’.
‘The above is the end of my diary as far as I am able to give. The following are points which I think would be of use: –
At no time throughout the operations was the Regiment short of food and ammunition.
I understand that on the afternoon of 29th the Brigadier ordered that all guns and equipment be destroyed and the dismounted Regiment to march with his Brigade. Most of them were killed or captured on the 30th.
