 He wrote a letter back to Mr. Jack Matthews in La Plata from West Sandling Camp September 5th, 1915 on 21st Battalion letterhead:

Dear Jack,

I feel sure you will be surprised to hear from me, however I trust the surprise won't be an unpleasant one. There is hardly ever any time for letter writing for we have been very much on the go since our arrival in England last May.

At last our training is at an end, and we are ready for the front. The King and Lord Kitchener inspected us Thursday and I understand the whole Division made a wonderful showing.  We leave for France next Thursday to do our little part in the great struggle and honestly I can hardly wait to get there. We all feel extremely bitter towards Germany on account of her many unpardoned atrocities, and I know when the time comes we shall go at them with all the strength we possess.

I wish you could see our Camp. We are situated on a very high hill overlooking the English Channel two miles away, and all around us are smaller hills and little valleys and hedgerows everywhere and they are always green for the sun is never too hot to parch them. It is truly a beautiful country, and the people are fine.

I was up in London a while ago for several days with one of the fellows in our company whose home is there. It was my first leave of absence and I truly enjoyed it. We spent most of the time sight seeing, but what I enjoyed most of all was the little touch of home life which as you know has always appealed to me. The people there think a whole lot of the Canadians on account of their brave fight at the battle of Ypres where they saved the left flank of the British and French Armies.

I declare they stop you on the street and ask you to go to the theatre or take an auto ride. Was down to Ramsgate to see the damage done by a Zeppelen (sic) in a recent raid, and on the way back stopped at Canterbury to see the old Cathedral there.

Mary Allison frequently sends me a new photo of little Warren Trowbridge and he is certainly a great looking kid. She also gives me detailed accounts of how he is progressing and the number of pounds he weighs which certainly amuses me for really I don't know much a baby should weigh. I know how happy she is, and indeed it makes me happy too at the thought of it.

When you get the chance please write to me for it would certainly afford me a great deal of pleasure. I think of you and all "back home" ever so often and while absent in body I am forever there in spirit. Good luck and happiness to you always, and my love to all at "Iduln."


Harry White

At this point I do not have the records or details of his service, but he joined the United States Army with the rank of Lieutenant and went to France with the 20th Aero Squadron, known as The Mad Bolshevik Squandron, as an Observer, flying in Dehaviland DH-4 aircraft number 32904.


On October 10, 1918 his aircraft was hit by an "Archie" while over the German lines at a height of eleven thousand feet. The plane was seen to turn and start gliding towards the American trenches, but, at about six hundred feet, they apparently encountered a strong German barrage which riddled his plane with bullets and killed both him and his pilot, Lieutenant William Clarkson Potter.  They were both buried by the Germans at Barricourt, Ardennes, near Stenay.  Following the war, both remains were transferred to the Suresnes American Cemetery and reburied side by side.

Another eye witness, pilot William S Holt of the 20th Sqn, described what he saw in a 1980 interview:

"Little Willie Potter.....I remember so clearly seeing him go down.  Potter was right over on my right wing and I was looking over there and the Germans were coming in.  I saw this one particular German plane come in and turn - and Potter's gas tank burst into flames.   The plane turned over and it went down.  Poor little fellow!  It is traumatic.  I had seen others go down befoe, but this was the most vivid.   (Potter's observer) Harry Wilmer was a Canadian.  Why he was in the American Army, I do not know.  He had been on the ground with the British Army and had won a Military Medal."

In addition there is this entry from "Over the Front", Volume 22, League of WW1 Aviation Historians:

"On 10 October, Ltn Leibfried and Vzfie Trautmann downed DH-4s of the 20th Aero Squadron DH-4 No 32904 flown by 1st Lt WC Potter and 1st Lt HW Wilmer (KIA) over the forest by Fey-en-Haye."


Dec 10, 1923

1914-15 Star, British War Medal and Victory Medal were sent to his father, L Allison Wilmer, c/o Wilmer & Ching, Leonardtown, Maryland USA 

Because he was discharged from the CEF and serving with the American Expeditionary Force, there was no Memorial Cross issued. 

The American Legion at 6330 Crain Highway, La Plata Maryland is officially named The Harry White Wilmer American Legion Post 82.
