Document Source: Memorandum on the Capture and Subsequent Escape of D.61182, P.S.M. Lucien Adhemard Dumais (Fus. M. R.) Operation Jubilee, Dieppe, France, 1942

[1] No Canadian Intelligence Officer was present at the detailed examination of PSM Dumais conducted by MI.9. The information included in this memorandum was obtained at an interview that took place on October 23, 1942, 2 days after PSM Dumais’ return to the United Kingdom.

[2] On August 19, 1942, at 0700, PSM Dumais landed from an R craft on the beach at a point 50 yards east of the Casino. This craft contained 20 men from N°3 (Mortar) Platoon, Headquarters Company, Fusiliers de Mont-Royal. Only six men had time to jump ashore before the craft containing the other 14 men and the mortars backed away and put out to sea again. PSM Dumais shouted to the Naval personnel in charge of the craft to put about again but his efforts were unsuccessful.

[3] PSM Dumais and the 5 other men from the Mortar Platoon found themselves alone on the shore midway between 2 beached Troops Landing Craft, one of which was burning furiously. They were at once exposed to heavy fire from both flanks and there were casualties almost immediately.

[4] Working his way westwards PMS Dumais met Lt Loranger, Commanding Officer of the N°3 Mortar Platoon, who had made a separate landing with another section of his Platoon. Lt Loranger had been seriously wounded and ordered PSM Dumais to take over the command of the Mortar Platoon.

[5] Followed by Cpl A. Vermette and others, PSM Dumais made for the Casino, which by that time had been cleared of enemy troops. On the way, they found a mortar abandoned by the RHLI (Royal Hamilton Light Infantry) and took it along with them, but as they could find no ammunition they left it behind before actually reaching their first shelter; a sand-bagged position behind the Casino.

[6] While in this shelter they were bothered by Machine Guns fire from a house opposite, but Cpl Vermette finally managed to put the enemy position out of action by fire from his Bren Gun.

[7] PSM Dumais’ party then entered the Casino proper and worked their way into the east wing. There, 2 enemy POWs were discovered who were at once passed on to the beach for embarkation. While in this part of the building PSM Dumais made a search for documents in a room that had obviously been used as living and office quarters by enemy troops.

[8] The party then went to the west wing of the Casino where Cpl Vermette knocked out 2 more enemy Machine Guns by fire from his Bren Gun. Some RCE personnel helped PSM Dumais’ party to blow the door of a steel safe in this part of the building.

[9] It was approximately 0800 and PSM Dumais went up to the second floor to help organize the defense in that quarter. He then made his way along a trench to a shed on the south of the Casino where he established contact with a lieutenant of the Royal Hamilton Light Infantry who appears to have assumed command of operations on the Casino and its immediate vicinity. From this shed, PSM Dumais was able to observe several British tanks in action. He saw one silence an enemy pillbox to the southeast of the Casino while another, after receiving several direct hits from an anti-tank gun, succeeded in putting the gun out of action and then continued on its way. Incidentally, the successful passage of these tanks effectively disposed of an enemy mortar that had been harassing the party in the Casino.

[10] By 1000, enemy fire had diminished to an appreciable extent, though there was still some sniping from the steeple of the St Remy Church. PSM Dumais engaged these snipers himself with another Bren Gun and succeeded in silencing all fire from that quarter.

[11] An attempt was then made, using a Wireless Transmitter from the Royal Hamilton Light Infantry, to establish radio contact with our forces elsewhere and inform them that the position in the casino was now favorable. When these efforts failed, PSM Dumais went back to the beach, where he collected 6 more men to augment the force in the Casino, which numbered about 30 in all ranks.

[12] At about 1230, a plan to attack across the street to the south had to be abandoned because of a lack of smoke bombs for the 2-inch mortars. As the craft was then observed approaching the beach, the Lieutenant of the Royal Hamilton Light Infantry gave the order to withdraw. He himself remained behind to cover this withdrawal and was assisted in this task by a sergeant of his own regiment and by PSM Dumais.
