My first match would have been approximately 1971-2.
I remember drawing a picture of the game at Gregory Street Infant Skool afterwards. The opposition wore yellow shirts (and so may have been Cas?) and won.
The experience was clearly underwhelming, as my second Batley match wasn't until the "Centenary Game" against Fulham in 1980.
I remember Fulham (in their first season) needed to win the game to gain promotion to Div 1, but the Gallant Youths beat them 10-8. Fulham scored a late try, but missed the conversion.
"What a team!" I thought (meaning Batley), "I'll buy a season ticket."
And so the journey began...
