After exuberant celebrations by members of both Oxford detachments, all the men were moved to Exeter College, thus, as it were, sequestering the Americans; the\u00a0<i>War Birds<\/i>\u00a0entry for October 22, 1917, provides a colorful account of the celebrations and their aftermath. William Ludwig Deetjen, who had been in charge of the men at Queen\u2019s, wrote in his diary on October 23, 1917: \u201cAnd then at noon we got orders to pack up and move to Exeter.\u00a0.\u00a0.\u00a0. Now Exeter has no hot water, rotten meals, baths only from 2:30 to 4:00 P.M. and it is really uncomfortable. Queen\u2019s College was heaven compared to this cold dump.

They were among ten who were sent to Nos. 2 and 4 Training Squadrons at Northolt aerodrome, located at Ruislip in northwest Greater London (the others were Edward Frank Hollander, Field Eugene Kindley, Walter Burnside Knox, Dudley Hersey Mudge, Reuben Lee Paskill, Roland Hammond Ritter, John Chadbourn Rorison, and Joseph Frederick Stillman, Jr.)\u00a0 \u00a0Matthiessen returned briefly to Grantham to take part in the Thanksgiving celebrations there.<a id=\"LinkTo_WPFootnote8a\" href=\"#WPFootnote8a\">8a<\/a><\/p>\n<p>At Northolt, when weather permitted, the cadets began flying instruction on Maurice Farman S.11 Shorthorns, flying \u201cdual\u201d with an instructor.

James Ira Thomas Jones (\u201cTaffy\u201d Jones) was training there and recalled the influx of Americans: \u201cOur school was lucky enough to get such grand types as Ken [<i>sic<\/i>] Curtis . . .

Morrison.\u201d<a id=\"LinkTo_WPFootnote11\" href=\"#WPFootnote11\">11<\/a> The aerodrome and accommodations were in general primitive, but some of the American cadets were lodged at the Red Lion in nearby Radlett where, as Marvin Kent Curtis wrote his sister, they were \u201cmore comfortably settled than at any other place I have been in the R.F.C.\u00a0.\u00a0.\u00a0.

On March 6, 1918, Pershing forwarded the recommendation for his commission to Washington; approval came back on March 17, 1918, and Matthiessen was placed on active duty on March 28, 1918.<a id=\"LinkTo_WPFootnote14\" href=\"#WPFootnote14\">14<\/a><\/p>\n<p>By this time, Matthiessen was at No. 56 Training Squadron, across the field at London Colney from No. 74.

In the same letter Curtis describes beginning to train on what are evidently Spads\u2014although, wary of censorship, he does not actually name the type of plane\u2014and it is likely that Matthiessen was making the same transition.<\/p>\n<p>From London Colney, Matthiessen would presumably have gone to Turnberry on the west coast of Scotland to train in aerial gunnery. His last training posting was at the No. 1 School of Fighting a little way up the coast at Ayr, where he would have trained on S.E.5s and\/or S.E.5a\u2019s. His R.A.F. service record notes that on July 7, 1918, he proceeded from \u201c1 Sch Fight\u201d to \u201cB.E.F.,\u201d i.e., to the British Expeditionary Force in France, and that he was an \u201cS.E.5 Pilot.\u201d<a id=\"LinkTo_WPFootnote15\" href=\"#WPFootnote15\">15<\/a> His casualty form, a record of active service postings, puts him at \u201cNo. 2 ASD\u201d on this date, i.e., at the pilots pool at Rang du Fliers, near Boulogne, part of the No. 2 Aeroplane Supply Depot. There he would have waited to be assigned to a squadron; Austin Finley Morrison, according to the latter\u2019s casualty form, joined him the next day.<a id=\"LinkTo_WPFootnote16\" href=\"#WPFootnote16\">16<\/a> Like many others, they had to kick up their heels at No. 2 A.S.D. for a while, but eventually, on July 21, 1918, they were assigned to No. 74 Squadron R.A.F.\u2014which meant they were back with many of the men they had trained with at London Colney. (Their fellow second Oxford detachment member, Alexander Miguel Roberts, had also been with No. 74, but had two days previously been shot down and made a prisoner of war.)<\/p>\n<p>No. 74 Squadron flew S.E.5a\u2019s and was stationed from April through September 1918 at Clairmarais near St. Omer, initially at Clairmarais Nord (where a casual photo of the squadron, including Matthiessen, was taken) and then, from early August at the newer aerodrome, Clairmarais Sud, only about a mile away.<a id=\"LinkTo_WPFootnote17\" href=\"#WPFootnote17\">17<\/a>\u00a0The squadron, commanded by Keith Logan Caldwell (\u201cGrid\u201d Caldwell), was part of the 11<sup>th<\/sup> (Army) Wing, II Brigade, attached to General Sir Herbert Plumer\u2019s Second Army; the Second Army front ran approximately from Houthulst Forest south past Ypres to Nieppe Forest.<a id=\"LinkTo_WPFootnote18\" href=\"#WPFootnote18\">18<\/a><\/p>\n<p>From the Clairmarais aerodromes the pilots of No. 74 Squadron flew line and offensive patrols as well as, occasionally, escort, ground strafing, and wireless interception missions, all the while seeking to put enemy reconnaissance planes out of commission and to eliminate enemy scouts flying over and east of the Second Army front north and south of Ypres\u2014all this is apparent from the account of No. 74 Squadron provided by Ira Jones in his\u00a0<i>Tiger Squadron<\/i>. As with a number of other squadrons, the squadron record book and other relevant original documents appear not to have survived, and I can thus not provide details of Matthiessen\u2019s activities. I find neither casualty nor combat reports for him, suggesting that he was not involved in incidents that resulted in injury to him or damage to his plane, and also that he made no combat victory claims. That he was assigned to C flight is supported by his appearance in an undated photo of that flight, along with Clive Beverly Glynn (apparently the flight leader), Harold Goodman Shoemaker, Frederick Stanley Gordon, John Adamson, Jr., and William Couper Goudie.
