Ar ddyddiau braf o haf, pnawn perffaith yn y Parc Cenedlaethol Eryri, roedd ysbyty maes gyda'i babell wen agored i'r gwynt yn brysur.

On beautiful summer days, a perfect afternoon in Parc Cenedlaethol Eryri (Snowdonia National Park), the field hospital with its white tent open to the wind was busy.

Roedd cerddoriaeth o'r ŵyl gefndir yn clywed yn y pellter, tra nad oedd y mynychwyr yn disgwyl unrhyw drafferth.

Music from the background festival could be heard in the distance, while the attendants expected no trouble.

Gyda'r haul yn bwrw ar lawr gwyrdd y bryniau, roedd Emrys yn sefyll wrth y drws, ei olwg yn bryderus ond yn benderfynol.

With the sun casting over the green floor of the hills, Emrys stood by the door, his look concerned but determined.

Roedd e'n wynebu dydd heriol.

He was facing a challenging day.

"Emrys, mae angen cymorth arnom!

"Emrys, we need help!"

" galwodd Aneira, nyrs brofiadol, gyda llais tawel a sicrwydd yn berwi o'i bresenoldeb.

called Aneira, an experienced nurse, with a calm voice and confidence brimming from her presence.

Chwyrodd Emrys ei ysgwyddau a chymerodd anadl ddofn.

Emrys shrugged his shoulders and took a deep breath.

Roedd y diwrnod hwn yn ddiwrnod o brofi ei allu.

This day was a day to test his ability.

Fe ddechreuodd drefnu'r cleifion i mewn i grwpiau yn seiliedig ar eu hanghenion.

He began organizing the patients into groups based on their needs.

Roedd rhai'n dioddef o olion blinder, tra bod eraill â mân anafiadau.

Some were suffering from fatigue, while others had minor injuries.

Yn y gorau o'r eiliadau, roedd Gwenny, nyrs ifanc a newydd, yn teimlo'r gwasgedd yn codi.

In the best of moments, Gwenny, a young and new nurse, felt the pressure rising.

Edrychodd hi ar Emrys.

She looked at Emrys.

"Beth mae'n rhaid i ni ei wneud nawr?

"What should we do now?"

" gofynnodd hi.

she asked.

Roedd 'na alw am ddewis rhwng dilyn cynllun Emrys neu lynu at yr hyn oedd hi'n gwybod.

There was a call to choose between following Emrys's plan or sticking to what she knew.

"Rydyn ni'n gweithio mewn tîm.

"We're working as a team.

Gadewch i ni ddosbarthu'r tasgau," dywedodd Emrys, ei lais yn bendant.

Let's distribute the tasks," said Emrys, his voice firm.

Roedd ei gynllun yn gyfrifoldeb newydd iddo, ond roedd teimlad rhyfeddol o hyder yn dod i'r amlwg.

His plan was a new responsibility for him, but a curious feeling of confidence emerged.

Tra oedd eu gweithgareddau'n llwyddiannus, tua'r hwyr cafodd hiker anymwybodol ei gario mewn.

While their activities were successful, towards the evening, an unconscious hiker was carried in.

Tynnodd Emrys o'i stor o hyfforddiant, gan drefnu prosesiad uniongyrchol ar gyfer cymorth.

Emrys drew from his training, organizing a direct response for assistance.

Arweiniodd y tîm, gyda Gwenny yn dilyn yn llwyddiannus.

He led the team, with Gwenny successfully following.

Wrth i'r haul suddo, daeth llwyddo i anogaeth.

As the sun set, success turned to encouragement.

Edrychodd Aneira ar Emrys gyda llawenydd cyfrinachol.

Aneira looked at Emrys with a secret joy.

"Wnaethoch chi lwyddo dan bwysedd," wrthododd hi, taflu ysgytwol o gydnabyddiaeth.

"You succeeded under pressure," she noted, casting a shivering acknowledgment.

Roedd Emrys wedi ennill ei barch.

Emrys had earned her respect.

Drwy'r llais clir o'r mwsig, daeth rhyw synnwyr o ddistawrwydd i'r babell.

Through the clear echo of the music, a sense of calm came to the tent.

Roedd y cleifion wedi cael gofal, ac wrth edrych ar y bryniau gwyrdd, roedd Wney yn teimlo ei hyder newydd.

The patients had been cared for, and looking at the green hills, Gwenny felt her newfound confidence.

Roedd hi wedi dysgu manteisio ar ei synnwyr, wedi cyrraedd at newidiadau yn llwyddiannus.

She had learned to rely on her intuition, successfully adapting to changes.

Er nad oedd yr hŵyl nad oedd yn un arall, roedd y diwrnod yn un i'w gofio.

Although it wasn't another event, the day was one to remember.

Roedd y bobl ffyddlon hynny yn teimlo cariad mawr tuag at eu swydd.

Those faithful people felt a great love for their work.

Roedd hi'n haf go iawn, llawn o her a chyflawniad, dan awyr Eryri.

It was a real summer, full of challenge and accomplishment, under the Eryri sky.
