I ran across this fascinating story from a local history blog and couldn’t wait until November 11 to post it… Jim Alexander was a resident of Hespeler, Ontario and a Corporal with the Lincoln and Welland Regiment in WWII. In March 1945 he was in Veen, Germany when he was ordered back to England to be decorated by the King for bravery.
Although greatcoats were supplied to soldiers when needed, Alexander’s regiment was awaiting supplies, including greatcoats, and so he gave his coat to a fellow soldier before leaving for England. Upon arriving in rainy, cold Aldershot, Alexander went to a Red Cross Centre where he picked out a khaki, hand-knit wool sweater. After receiving his medal for bravery, Alexander rejoined his regiment and was given a new greatcoat. The sweater was packed away in his kit.
When Alexander returned home to Hespeler in January, 1946, his mother found the sweater as she sorted through his clothes for laundry. She recognized it as one she had knitted herself and proved it by snipping the seam between the double collar to reveal a two dollar bill with a hand written note in her hand requesting the recipient to write her to let her know how he was doing. Apparently it was common for women who had knitted socks, scarves, and sweaters for overseas to include money and notes in the hems and seams of their garments. It was pure coincidence that Alexander had picked the sweater his own mother had knitted and yet never looked inside the collar.
Added 19.9.14: Here is a similar story about a note found in WW1 kilt.
