It is very common to see milky looking oil in the back end of old thousand series Ford tractors and Massey 65 tractors from years of condensation and oil not being changed. No harm was ever done. Fix the hose and change the oil you should not have any problem.
Don't feel so bad about things; I have a D4D here that sat outside and collected plenty of moisture inside the case. It is nice and creamy. I will drain and flush if necessary before refilling. Just another part of maintenance. JM
Take the swivel nut off the hose and the fitting out of the cylinder ,take the parts to a hyd store and get new one.
Pick up more oil, drain what you can out of tank and refill .

I got a new hose, refilled the tank and im thikning of losening up the hoses on the other cylinder to help "push" the milky oil out of the cylinders for a couple days then refill again and tighten up all the hoses. Then Im thinking maybe I will drain again with the hand pump and refill with new oil in a couple weeks
