Blencowe John Elmer, 1894, New York, Private First Class, 1737424, 312th Infantry Coy F, 78th Division.
- 1st Apr. Enlisted at Camp Dix New Jersey, with the 312th Infantry, which was part of the 156th Infantry Bde., 78th Division AEF.
- 23rd Apr. Jack was mobilised at Camp Dix, New Jersey. The 78th Div. consisted of four Infantry Regiments – the 309th, 310th, 311th and 312th and three Artillery Regiments – the 307th, 308th and 309th.
- 20th May. Records show that this day Jack and 312th Infantry Coy. F along with Coy. E travelled by train to Boston and embarked for Europe on the ship SS Winifredian.
- 2ndJun. SS Winifredian came under submarine attack, but British destroyers took care of the submarines. The 312th Infantry disembarked in England went to Folkestone stayed for just a few days before embarking to Calais and then on to Senlecques for training by British troops.
- 10th May-6th Jun. The entire 78th Division arrived at different English ports. They soon thereafter departed for France. After training with British instructors at St Pol behind the Arras front in France, the 312th was ordered to St Mihiel.
- 27th Aug. Moved from Jonvelle and marched for 2 days to reach the village of Germainvillers and billeted there.
- 2nd Sept. Marched overnight to Bilgneville then onto Dolaincourt.
- 10th Sept. By truck all night through Neufchateau and Toul to a large woods near Domevres-en -Hey.
- 11th Sept. By truck again overnight arriving on the 12th at Bois de Larappe.
- 12th Sept. St. Mihiel Offensive. Positioned as Corps reserves behind the 2nd, 5th, and 90th Division in the front. The attack at the St. Mihiel Salient was part of a plan by General Pershing in which he hoped that the United States would break through the German lines and capture the fortified city of Metz. It was one of the first U.S. solo offensives in World War I and the attack caught the Germans in the process of retreating. This meant that their artillery was out-of-place and the American attack proved more successful than expected.
- 10th-15th Oct. Argonne-Meuse Offensive. The 312th Inf. marched to the Argonne and remained in Reserve behind the Grandpre Front.
- 15th Oct. 78th Div. takes over the line from 77th Div. the 312th Inf. facing directly Grandpre, with other units of the 156th Bde. facing Chevies, Bois des Loges and Cote 182. Grandpre and Bois des loges were enemy Machine Gun nest traps making attack deadly.
- 16th -25th Oct. Argonne-Meuse Offensive (Grandpre) The 312th and the 78th Div involved in attacks at Champigtieulle, Grandpre, Bois des Loges. At 06:30 hrs on the 16th Oct. the 2nd Bn. of the 312th began attacking Grandpre the enemy had previously beaten off units of the 77th Div. and were lodged in the upper floors of buildings in the town. However, by 11:00 hrs the 312th had captured 34 prisoners and taken half the town. It took five days of house-to-house fighting to complete the capture of the rest of the town, except the citadel. Further west, 1st Bn. 312th, and a machine gun company, forded the river in the morning under heavy machine gun and artillery fire, with difficulty, established liaison with the French at Echaude Farm and dug in along the Grandpre-Termes Road.
- 23rd Oct. Capture of Grandpre. After a couple of days of planning after failing to take their targets the 312th again stormed Grandpre. The attack on Talma Hill was successful. The battalion objective was gained and patrols sent out along the southern edge of the Bois de Bourgogne. Seventy-eight prisoners were taken on the citadel, one man in Company K, 312th, taking 47 of them out of one dugout. While the full objective set for this attack was not reached, two of the three points which make up the stronghold of Grandpre were taken; Talma Hill and the Citadel in Grandpre.
- 24th Oct. The 312th was relieved of its position and went into Div. reserve. The capture of Grandpre and the Bois-Loges by the 78th Div. was the breaking of the Hindenburg Line the pivot of the German defence.
Note: The brothers George W and John E Blencowe were both in the Argonne Forest in October, most likely after the war, these were times remembered from the war together.
- 1st Nov. Ferme des Loges. In an attack on German firing positions, 312th Inf was able to attack the Ferme des Loges with grenades and put out a number of the guns.
- 2nd Nov. The Pursuit Toward Sedan. On the left, contact was gained with the enemy just as he was withdrawing from Boult-aux-Bois. A patrol, followed by Company C, 312th, entered the town and followed the Germans north to Belleville-sur-Bar, which they captured at noon. At Boult-aux- Bois, our men joined up with the happy, rejoicing French troops, who had come upon the west side of the Bois de Bourgogne. Further east other troops of the 312th, had driven the enemy out of Germont at 09:30 hrs, and then advanced detachments north through Authe toward Brieulles-sur-Bar and west toward Chatillon-sur-Bar.
- 4th Nov. Leading elements of the 312th Infantry also reached Les Petites Armoises, advancing via Bazancourt Farm from Chatillon and maintaining contact with the French.
- 5th Nov. The 312th Infantry occupied the line to the northwest of Tanney, connecting with the French, who in the meantime had advanced abreast of our line, on the west side of the Ardennes Canal. On the afternoon of the 5th our line, therefore, extended, on the left, from the Ardennes Canal northwest of Tanney, across the Tanney-Sedan road just south of the Bois du Mont Dieu, along the high ground east of Tanney, and thence southeast through the town of Sy.
- 11-13th Nov. The Armistice. The division was billeted in several small villages radiating from Ste. Menehould. Here they were given bathing facilities and new underclothing was issued. All attention was centred on cleaning up during these three days. Refreshing baths, clean clothes and these few nights peaceful sleep put all hands in high spirits again.
