Good luck Flag To honor fallen WWII Japanese soldiers (museum display)

looking for someone to translate the names and slogans on this flag for record in our museum. The flag will be part of a display with other artifacts honoring the Japanese soldiers who sacrificed themselves honorably for their country. we want to show those who visit that regardless of cultural differences...both sides were just regular people, and not the raciest stereo types that each country's government propaganda portrayed .
Thank you

There is a slogan 頑張れ松田君 Do your best, Matsuda on the flag, thus, the recipient name of the flag is Matsuda. Also, one of the dedicators is 水橋青？学校長 the principal of a school in Mizuhashi; a region in Toyama city, Toyama prefecture, so Matsuda might be from there.

Other slogans are;
若鷲
Young eagle

神州鎮護
Protection of the divine country

滅敵！！
Destroy the enemy!!

呑敵
Overawe the enemy

忠
Loyalty

敢闘
Fight bravely

善戦善闘
Fight well, battle well

撃って呉れ
Shoot

特攻精神
Suicide attack spirit

成徳
virtue practicing

祈武運長久
一意神風よ續け
貴君よ？？力で通也
軍人勅諭常有心
Eternal good luck in battle
I pray wholeheartedly that divine wind continues to blow.

The rest are all signatures.

Amazing! thank you so much for your help! about the signatures, are they simple names, or names and titles as in the name denoting "principal"? is there anything that may be a clue as to the date or year of this piece?

Unfortunately, the signatures are just names and there is nothing mentioned about the date.
Incidentally, the flag is upside down in the picture.
