Recovering a wallet

I had LTC in a wallet on a HDD that has been physically damaged. I had no backup.
I don’t recall ever being given a secret address for it.

I know the wallet address, and the transaction addresses and blocks.

I have created a new wallet on a new PC.

How do I transfer the LTC from the old wallet to the new one? (In non-tech speak please)

Thanks.

you can’t without the private key of the old wallet.
