Dear Mary
This was taken while gardening and digging up ground for potatoes to be planted for the troops. Some old pot took it 4 each. A most remarkable thing to us happened today. Yesterday we were isolated for mumps and measles etc and today we were transferred from hut 30 to a new lot of huts ours is 13 the wash house is no 3.
Note Thorpe marked X, McGowan 14 stone next to me. What do you think in the name H.M.A.T. WILTSHIRE 13 words.
Tomorrow will be the start of 13 weeks since we left Brisbane. Will we have luck or not? I was put as Corporal over the Chows and was told if anyone got away I would go in the clink.
We saw a great sham? fight today at Hurdcott visitors were here and two fellows got badly hurt one lost his eye
gas, bowls, cricket anything. Pretty to see.
I was luck again left watch in bath room for 15 minutes and got it.
Watch losing again 10 minutes each day.
Love and kisses, Harold
